description: ZnxSn1-xSe (x=0) thin films were fabricated by chemical vapor deposition (CVD) using polycrystalline tin selenide (SnSe) precursors. The morphology, structure, optical and electrical properties of films were studied as a function of the composition of precursors and the substrate temperature. Results obtained have shown that Se rich films were fabricated at low substrate temperatures, despite the different compositions of the SnSe precursor during the synthesis. In this case, the grain sizes of the films vary in the range of 8-20 μm, depending on the substrate temperature. X-ray diffraction (XRD) analysis of the samples showed that the films have a orthorhombic crystalline structure. The optical measurements have revealed that the samples have optical bandgap of 1.21 eV and the absorption coefficient of ~105 cm-1. The samples performed p-type conductivity being in the range of 10-102 (Ohm×cm)-1 depending on the deposition conditions.

description: The installation of photovoltaic modules in the MENA region is very beneficial if we consider the high amount of solar irradiation received by this area. Nevertheless, the presence of soiling sources mainly from dust and sand storm reduces, significantly, the performances of this technology and increases the Operation and Maintenance (O&M) costs. For this reason, it’s crucial to find solution for dust removal, to enhance the modules optical efficiency, thus the electricity production. Super-hydrophobic coatings can be a good solution for this issue. In this paper, we
evaluated the soiling effect on three different PV glazing samples under the semi-arid climate of Benguerir in Morocco.
Furthermore, the coating performances were evaluated by comparing the transmittance drop of two glass samples with
two different coating layers based on SnO2 and SnO2F.
The results show that soiling is an immense problem in Morocco where the transmittance drop can reach 38% after 13 weeks of exposition. Furthermore, adequate coatings on glass can be a good anti-soiling solution. It is found that the SnO2:F coating on glass enhances the transmittance by 3.22% in comparison to 2.99% for SnO2 on glass.

Homojunction Solar Cells

description: We demonstrate an industrial double-side-contacted, screen-printed large area cell with POLO junctions on both sides and
an in-house-measured energy conversion efficiency of 22.3 % (A = 244.15 cm2, Voc =714 mV, FF= 81.1 %, Jsc =38.5 mA/cm2). Most
remarkably, this cell shows a very low series resistance < 0.05 Ωcm2, which supports previous observations of low specific junction
resistance for the POLO scheme. The current limitations of the cell are (i) the low short-circuit current due to parasitic absorption in
the rather thick poly-Si (30 nm), as well as in the ITO, (ii) deterioration of the recombination behavior upon TCO sputtering, and (iii)
shunts near the edge due to non-adapted TCO edge-exclusion.

description: Influence of Indium and Phosphorous on the GaAs photovoltaic cells has been studied. In, P diffusion was made from the gas phase in hydrogen flow atmosphere. The samples were characterized by secondary ion mass spectroscopy (SIMS), Raman spectroscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM). The p-n junction was formed by Zn diffusion from the gas phase. SERS experiment with Au nanoparticles revealed a strong reduction of As cluster concentration in subsurface region after annealing in In, P vapours. At the same time In-rich clusters are found in the annealed samples. A comparative study of PV cells prepared with and without In, P treatment was performed. It was found, that despite the higher Zn concentration in the emitter, surfactant-induced
modification of the surface results in higher external quantum efficiency at short wavelength region. Also it is found, that
p-n junction formed in the presence of surfactants reveals higher open circuit voltage and fill factor values of the I-V curve. As a result, 15-20% relative PV cell efficiency increase was observed with the In, P diffused samples.

description: We present a novel positive potential-density pair expansion for modelling galaxies, based on the Miyamoto-Nagai (MN) disc. By using three sets of such discs, each one of them aligned along each symmetry axis, we are able to reconstruct a broad range of potentials that correspond to density profiles from exponential discs to 3D power law models with varying triaxiality (henceforth simply "twisted" models). We increase the efficiency of our expansion by allowing the scale length parameter of each disc to be negative. We show that, for suitable priors on the scale length and height parameters, these "MNn discs" have just one negative density minimum. This allows us to ensure global positivity by demanding that the total density at the global minimum is positive. We find that at better than 10\% accuracy in our density reconstruction, we can represent a radial and vertical exponential disc over $0.1-10$ scale lengths/heights with 4 MNn discs, an NFW profile over $0.1-10$ scale lengths with 4 MNn discs, and a twisted triaxial NFW profile with 3 MNn discs per symmetry axis. Our expansion is efficient, fully analytic, and well-suited to reproducing the density distribution and gravitational potential of galaxies from discs to ellipsoids.

description: We propose in this communication a simplified and straightforward method for determining the lifetime of minority carrier in the materials for solar cells. This technique consists in placing the layer to be investigated between a p-n junction in the light-incident side, and measuring the extracted photocurrent for various illumination wavelength or layer thickness. Our strategy is close to extracting the diffusion length by fitting the EQE of a solar cell [1], but is more precise since the wavelength range carrying the relevant information is larger. As a support for this proposal, we
investigated the effects of n-dopant species, Te and S, on the properties of GaAs solar cells. The preliminary study showed that the carrier extraction was degraded with increasing layer thickness, and this effect was more pronounced in S-doped solar cells. The increasing doping concentration also deteriorated photo-current, and, in this case, influence of Te doping was more than that of S. In summary, this proposed methodology has been proved useful to investigate the properties of minority carriers in semiconductors.

description: Graphene and Perovskite (methyl ammonia lead halide: CH3NH3PbI3) interaction plays a vital role to couple
the electromagnetic (EM) field to sub wavelength structures and this field further merged with thin films for the Photovoltaic.
Perovskite illustrates a tunable behaviour like organic and inorganic materials while dielectric function of graphene can be
tuned by varying its thickness. The study of such coupled system is useful to understand the physics of plasmonic behaviour of metal-dielectric interface. In present work, we have studied the coupling of EM field with noble Metal Nano-particles
(MNPs), that supports localized surface plasmon resonance (LSPR). This interaction controls the resonance band width and
full width half maxima (FWHM) of the resonance band under the quasi-static approximation for the core-shell spherical
nano-geometry. In this geometry, core is metallic (Cu) and shell is graphene mono-layer (GML) embedded in two different
media of air and perovskite matrix. The optical parameters such as extension efficiency and SPR tunability were studied from
ultra-violet to infrared domain (310nm -1400 nm), which steer a wide range of AM1.5 spectrum. There is a blue shift in SPR
peak as we increase the core radii from 11 nm to 19 nm. The tunability of SPR peaks of Cu-GML nano-geometry is strongly
dependent of the thickness of GML (varies from 0.1 nm to 0.6 nm). As the size of NPs or core-shell increases, there is a red
shift in the resonance peak. We have also analysed that extinction efficiency for Cu-GML is higher in perovskite medium
than air. Without graphene, LSPRs of NPs do not show appreciable shift in resonance wavelengths, which demonstrates the role of graphene as an electromagnetic field coupling agent.
The requirements for PCP signalling in early zebrafish endoderm morphogenesis
Creators: name: Miles, Lee Barry
Publisher: name: Monash University

Subjects: Uncategorized

description: The vertebrate endodermal cell layer gives rise to the intestine and related organs such as the liver and pancreas. The endodermal organs control many critical metabolic processes including the absorption of nutrients, homoeostasis of blood sugar levels, and detoxification of the blood. The cell fate specification and organogenesis of the zebrafish endoderm is well characterised, however the morphogenic processes during migration to the midline at somitogenesis stages and the formation of the primitive endodermal rod were unknown. This study used the Tg(sox17:EGFP) endodermal reporter line to determine the process of endoderm development at somitogenesis stages during two important phases of morphogenesis, the migration to the dorsal midline, and the formation of the endodermal rod (termed “midline aggregation”). Analysis of the polarisation of the microtubule organising centre (MTOC) in respect to the direction of cell migration reveals a contrasting difference between the endoderm and the surrounding mesoderm, indicating the directed migration of these two cell types are not regulated by the same mechanisms. The Planar cell Polarity (PCP) signalling pathway is known to regulate convergence and extension (C&E) movements of the mesoderm and ectoderm (Topczewski et al., 2001; Jessen et al., 2002). This study analysed endodermal development in the PCP mutants trilobite and knypek, and reports on the requirements of individual components of the PCP signalling pathway for endoderm development and morphogenesis during somitogenesis stages. The role of PCP signalling components during brain morphogenesis was also investigated, identifying a requirement of specific PCP signalling components for brain vesicle expansion. This study also describes the generation of a transgenic line that enables the inducible disruption of the PCP signalling to analyse the time-specific roles of this signalling pathway during development. This novel transgenic line enabled the identification of a time-specific role of PCP signalling in the regulation of hindbrain axis morphogenesis.

Metadata

description: The Metadata Hub provides a generic service for metadata repositories. Based on this, different kinds of metadata repositories can be accessed with uniform tools without the researchers having to deal with the complex details. In the domain of research data management, there are a variety of repositories that offer metadata management services to researchers. This poses the challenge that these repositories usually have different interfaces and in nature are not very interoperable with each other, violating one of the FAIR Principles. Our work aims to build a bridge between these repositories as a generic service for metadata repositories, the Metadata Hub. It’s accessible via the Turntable API, which defines a uniform interface for metadata repositories. To validate metadata documents, a definition of the document structure has to be available. For JSON/XML, there is JSON/XML Schema for this purpose. In case of JSON-LD, JSON Schema is not sufficient. Therefore, so-called application profiles are used, which are defined by using Shapes Constraint Language (SHACL). In general, the Turntable API is split in two parts: The first part is about managing (CRUD) ‘schemas/application profiles’ which are describing the structure of metadata documents, extended by the ability to validate a metadata document against a registered ‘schema/application profile/…’. The second part is about managing the metadata documents itself based on one of registered ‘schemas/application profiles’. Currently, we build the Metadata Hub as a Demonstrator mapping two completely different repositories (Coscine, MetaStore) as a showcase. The Metadata Hub is powered by the Metadata Hub Framework and provides a web interface to make the service available to a broad mass. This work has been supported by the research program ‘Engineering Digital Futures’ of the Helmholtz Association of German Research Centers, the Helmholtz Metadata Collaboration Platform and the German National Research Data Infrastructure (NFDI).
Leaf litter breakdown in streams of East Malaysia, Borneo: a study of biodiversity and ecosystem functioning
Creators: name: Jinggut, Tajang
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Litter decomposition in streams represents an important terrestrial-aquatic link in tropical forests and studies have shown that detritivore shredders are more abundant in temperate than tropical streams because the feeding guild is believed to be more adapted to cool waters where there is greater availability of high quality resources. I hypothesized that this global variation in shredder distribution may be observed at local scales in tropical regions along an altitudinal gradient and investigated the importance of shredders in litter breakdown using field-based techniques in streams flowing through the different forest types of East Malaysia (Borneo) that correspond to different altitudes (21 - 3393 m above sea level). I found evidence of increasing shredder abundance and relative abundance with altitude as a possible function of decreasing temperature and decreasing lignin concentrations in litter. The altitudinal variations in taxonomic composition of shredder assemblages were distinct between lowland streams that were dominated by semi-aquatic cockroach, beetle (Elmidae) and stonefly (Neumouridae and Cryptoperla) shredders, and highland streams that were represented by Cranefly (Tipulidae) and Caddisfly (Lepidostomatidae) shredders. Environmental effects on shredder distribution were detected, but this did not translate into a parallel functional trend of increased shredder-mediated decomposition of local riparian litter with increasing elevation. Initial nitrogen content of litter, which was not altitude related, was a strong and consistent predictor of decomposition rates throughout the study. Diversity of shredders in lowland streams ranged from 0 to 8, and species composition was highly variable. Conversely, in highland streams, diversity was more stable in terms of both species richness (range 3 to 5) and composition. The high variability, across lowland streams, has typically been observed in other tropical surveys of shredder distribution. We may have captured the effect of this variable distribution on decomposition, since biodiversity effects on decomposition were detected in our study. Whether this relationship is a direct function of species interactions through complementary or facilitative effects, or strongly mediated by the presence of large shredders typical to lowland streams, remains untested. The relationship between shredder communities and environmental conditions may be general, transcending local factors, because this association is observed at both latitudinal and altitudinal gradients. In contrast, ecosystem functioning may not follow this general trend since biodiversity effects on decomposition are highly specific, reliant on shredder species identity, functional traits, composition and interactions. Shredder community structure may show patterns across broad biological scales, but functional patterns would be reliant on the local interactions within these structures.

description: Light trapping is one of the major criteria to improve the solar cell performances. In the case of silicon based thin film solar cell texturization of front transparent conducting oxides (TCOs) is one of the practical ways for better light trapping by enhancing optical diffused transmittance and minimizing the reflection losses. A new method is adopted here; glass surface(s) is/are texturized instead of texturing the front TCO and is used in the fabrication of
silicon based thin film solar cell. We used two different textured patterns for two different sides of the glass. This textured glass is found to be highly effective in terms of their optical properties. Over 12% and 13% improvement of short circuit current density is noticed in the cell fabricated single junction microcrystalline and amorphous silicon solar cell respectively on both surface textured glass as compared to non-textured glass. Single junction
microcrystalline silicon solar cell (with simple p-i-n structure) and amorphous silicon solar cell with initial efficiency of 8.24% and 9.24% respectively are fabricated on this type of glass substrate without using back reflector.

description: We present the optical spectroscopic study based on 41 spectra of 4 Her and 32 spectra of 88 Her, obtained over a period of 6 months. We estimate the rotational velocity of these stars from He{\sc i} lines in the blue spectral region (4000--4500 Å). We find that these stars are likely to be rotating at a fractional critical rotation of $\sim$ 0.80. We measure the average $I_p/I_c$ ratio to quantify the strength of the H$α$ line and obtain 1.63 for 4 Her and 2.06 for 88 Her. The radius of the H$α$ emission region is estimated to be $R_d/R_*$ $\sim$ 5.0, assuming a Keplerian disk. These stars are thus found to be fast rotators with relatively small H$α$ emission region. We detect V/R variation of H$α$ spectral line during the observed period. We re-estimate the periods for both the stars and obtain two periods of $\sim$ 46 days and its harmonic of 23.095 days for 4 Her and $\sim$ 86 days for 88 Her. As these two are shell stars with binaries and have low H$α$ EW with the emission region closer to the central star, the V/R variation and a change in period may be an effect of the binary on the circumstellar disk.

description: High energy photons in the UV region are not efficiently used in solar cells and limit the overall efficiency of the cell. Luminescent Down-Shifting (LDS) layers can be used to convert the high energy photons to a lower energy before it reaches the cell, which is more efficiently absorbed. In this study, an investigation of the optics of polymer thin-films LDS layer when comprising of mixed organic dyes, against single dye thin-films was investigated. The effect of creating a layer comprising of an equal ratio of BASF Lumogen Yellow 083, Lumogen Orange 240, and Lumogen Violet 570 in a
polymethyl methacrylate (PMMA) polymer was investigated and compared to the experimental results from each single dye.
This aided in determining whether using multiple organic dyes in a single film was beneficial for use as an LDS material. The interaction of the dyes with each other was investigated. It was determined that the combination of dyes created a larger
absorbance range following the trend of each of the dyes it contained. The resulting emission of the mixed layer has an
emission peak at the wavelength matching the longest emission peak wavelength of the comprising dyes. Further tests
containing only two of the Lumogen dyes agreed with this finding.

description: CONTEXT. Exoplanet searches have demonstrated that giant planets are preferentially found around metal-rich stars and that their fraction increases with the stellar mass. AIMS. During the past six years, we have conducted a radial velocity follow-up program of 166 giant stars, to detect substellar companions, and characterizing their orbital properties. Using this information, we aim to study the role of the stellar evolution in the orbital parameters of the companions, and to unveil possible correlations between the stellar properties and the occurrence rate of giant planets. METHODS. Using FEROS and CHIRON spectra, we have computed precision radial velocities and we have derived atmospheric and physical parameters for all of our targets. Additionally, velocities computed from UCLES spectra are presented here. By studying the periodic radial velocity signals, we have detected the presence of several substellar companions. RESULTS. We present four new planetary systems around the giant stars HIP8541, HIP74890, HIP84056 and HIP95124. Additionally, we find that giant planets are more frequent around metal-rich stars, reaching a peak in the detection of $f$ = 16.7$^{+15.5}_{-5.9}$% around stars with [Fe/H] $\sim$ 0.35 dex. Similarly, we observe a positive correlation of the planet occurrence rate with the stellar mass, between M$_\star$ $\sim$ 1.0 -2.1 M$_\odot$, with a maximum of $f$ = 13.0$^{+10.1}_{-4.2}$%, at M$_\star$ = 2.1 M$_\odot$. CONCLUSIONS. We conclude that giant planets are preferentially formed around metal-rich stars. Also, we conclude that they are more efficiently formed around more massive stars, in the mass range of M$_\star$ $\sim$ 1.0 - 2.1 M$_\odot$. These observational results confirm previous findings for solar-type and post-MS hosting stars, and provide further support to the core-accretion formation model.

Manufacturing & Production

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 373-376
description: One of the main challenges within Si solar cell production is the increase of throughput rates. With
throughput rates in the range of 2400 Wafers / hour, metallization lines based on flatbed screen printing are typically
the bottleneck of a modern solar cell production. Within this work we present innovative printing technologies
allowing for higher throughput rates, e.g. rotational printing technologies as flexographic printing and rotational
screen printing and as well multi-nozzle dispensing. In principle, flatbed screen printing processes can be completely
replaced by using e.g. rotational screen printing for rear side printing and e.g. flexographic printing or dispensing for
front side printing.. Hence, the realization of higher throughput rates and thus lower production costs is addressed.
Moreover, new printing technologies allow for Ag paste savings up to 20% and efficiency increases of 1-2% relative
by optimizing the finger geometry.

description: In this work we present a new technology for simultaneously interconnecting and encapsulating bifacial busbarless solar cells, using a multi-wire approach combined with weaving technology. A background discussion on existing multi-wire interconnection technologies allows to compare this new approach, which
potentially improves performance and reliability and reduces process complexity and costs. After a more in-depth review of the weaving aspects, an extensive experimental campaign has been performed to optimize the combined interconnection/lamination process and obtain homogeneous solder joints. Preliminary thermal cycling tests have been executed, showing the stability and reliability of the solder joint contacts on 1-cell glass-glass laminates. Finally, the realization of a 2x2-cell-module proof-of-concept demonstrates the technical viability and performance of the technology.

description: We introduce an algorithmic approach based on generating tree method for enumerating the inversion sequences with various pattern-avoidance restrictions. For a given set of patterns, we propose an algorithm that outputs either an accurate description of the succession rules of the corresponding generating tree or an ansatz. By using this approach, we determine the generating trees for the pattern-classes $I_n(000, 021), I_n(100, 021)$, $I_n(110, 021), I_n(102, 021)$, $I_n(100,012)$, $I_n(011,201)$, $I_n(011,210)$ and $I_n(120,210)$. Then we use the kernel method, obtain generating functions of each class, and find enumerating formulas. Lin and Yan studied the classification of the Wilf-equivalences for inversion sequences avoiding pairs of length-three patterns and showed that there are 48 Wilf classes among 78 pairs. In this paper, we solve six open cases for such pattern classes.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 391-395
description: The crystalline/amorphous silicon heterojunction solar cell technology (SHJ) features among the
highest efficiency potentials of all cell architectures, but also the most stringent specifications regarding the substrate
quality. In this regard, multi-millisecond carrier lifetime wafers are mandatory to leverage the SHJ architecture
benefits. As a consequence, the content of recombination-active defects must be carefully controlled in the silicon
substrate, as strong efficiency reductions may otherwise arise. In this context, the presence of defects such as thermal
donors can severely limit the final device efficiency, and their presence in excessive concentrations should be
detected as early as possible in the cell process in order to better manage the cell production/understand the
performance variations. This paper introduces a novel technique, based on OxyMap measurements on as-cut wafers,
which allows an upstream prediction of the final device performance assuming that thermal donors are limiting the
carrier lifetime.

description: We address the dynamics of quantum correlations for a bipartite continuous-variable quantum system interacting with its fluctuating environment. In particular, we consider two independent quantum oscillators initially prepared in a Gaussian state, e.g. a squeezed thermal state, and compare the dynamics resulting from local noise, i.e. oscillators coupled to two independent external fields, to that originating from common noise, i.e. oscillators interacting with a single common field. We prove non-Markovianity (non-divisibility) of the dynamics in both regimes and analyze the connections between non-divisibility, backflow of information and revivals of quantum correlations. Our main results may be summarized as follows: (i) revivals of quantumness are present in both scenarios, however, the interaction with a common environment better preserves the quantum features of the system; (ii) the dynamics is always non-divisible but revivals of quantum correlations are present only when backflow of information is present as well. We conclude that non-divisibility in its own is not a resource to preserve quantum correlations in our system, i.e. it is not sufficient to observe recoherence phenomena. Rather, it represents a necessary prerequisite to obtain backflow of information, which is the true ingredient to obtain revivals of quantumness.

description: We investigate exclusion limits on the the non-universal gaugino mass scenario in the Minimal Supersymmetric Standard Model (MSSM), according the the latest results of the super-particle search at the LHC8 and the LHC13. In this scenario, suitable ratios of wino to gluino mass can realize the observed value of the Higgs boson mass, while keeping a small $μ$ parameter. Such a small $μ$ parameter corresponds to the mass of higgsino, so that lightest neutralino and chargino are higgsino-like and their masses are almost degenerate. Besides, we find that the right-handed top squark tends to be lighter than other sfermions and then the top squark search, where the top squark decays to a quark and higgsino, is relevant to our model. In our analysis, the exclusion limits are derived using the data of the top squark searches in the $bb + E_T^{\rm miss}$ and $tb + E_T^{\rm miss}$ channels. Furthermore, the exclusion limit on gluino mass, which is crucial to our scenario, is investigated as well. The analysis of the gluino is based on the data of the analysis with large missing energy and at least three b-tagged jets at the ATLAS experiment.

description: We study entanglement generation and control in bi-directional waveguide QED driven by a two photon Gaussian wavepacket. In particular, we focus on how increasing the number of qubits affects the overall average pairwise entanglement in the system. We also investigate how the presence of a second photon can introduce non-linearities, thereby manipulating the generated entanglement. In addition, we show that through the introduction of chirality and small decay rates, entanglement can be stored and enhanced up to factors of 2 and 3, respectively. Finally, we analyze the influence of finite detunnings and time-delays on the generated entanglement.

description: An expression for cell collection efficiency,
c, as a function of rear-surface internal reflectance, RB, is
presented, which derives from the Basore expression for internal quantum efficiency, IQE, in Si solar cells. Using
the expression for
c together with the Rand and Basore expression for effective optical path-length factor, Z, provides
a calculation approach for a self-consistent evaluation of RB,
c, and Z in textured cells, where
c and Z are determined
by RB. The calculation approach is applied in two reported Si solar cells and checked by using the numerical
simulation program PC1D.
A note on the Krylov solvability of compact normal operators on Hilbert space

description: We analyse the Krylov solvability of inverse linear problems on Hilbert space $\mathcal{H}$ where the underlying operator is compact and normal. Krylov solvability is an important feature of inverse linear problems that has profound implications in theoretical and applied numerical analysis as it is critical to understand the utility of Krylov based methods for solving inverse problems. Our results explicitly describe for the first time the Krylov subspace for such operators given any datum vector $g\in\mathcal{H}$, as well as prove that all inverse linear problems are Krylov solvable provided that $g$ is in the range of such an operator. We therefore expand our knowledge of the class of Krylov solvable operators to include the normal compact operators. We close the study by proving an isomorphism between the closed Krylov subspace for a general bounded normal operator and an $L^2$-measure space based on the scalar spectral measure.

description: In learning tasks with label noise, improving model robustness against overfitting is a pivotal challenge because the model eventually memorizes labels, including the noisy ones. Identifying the samples with noisy labels and preventing the model from learning them is a promising approach to address this challenge. When training with noisy labels, the per-class confidence scores of the model, represented by the class probabilities, can be reliable criteria for assessing whether the input label is the true label or the corrupted one. In this work, we exploit this observation and propose a novel discriminator metric called confidence error and a sieving strategy called CONFES to differentiate between the clean and noisy samples effectively. We provide theoretical guarantees on the probability of error for our proposed metric. Then, we experimentally illustrate the superior performance of our proposed approach compared to recent studies on various settings, such as synthetic and real-world label noise. Moreover, we show CONFES can be combined with other state-of-the-art approaches, such as Co-teaching and DivideMix to further improve model performance.

description: Gallium antimonide (GaSb) is an III-V semiconducting compound with a distinct lattice and band gap energy structure,
enabling innovative application in optoelectronic devices. As substrate material in device technology, it allows operation on
a wide spectral range i.e. 0.8÷ 4.3μm. Consequently, GaSb is an important competitor for solar energy conversion e.g. high
efficiency thermo-photovoltaic (TPV) cells. Nowadays, GaSb technology is devoted to the development of high quality
single crystals, efficient surface passivation techniques or competitive design of active p-n junction. The present work is
dedicated to the study of Si+ ion implantation in n-GaSb, with the aim of defining an active p-n junction at a precise level of
local doping. The n-GaSb substrates were chemically prepared by cleaning and selective etching, and afterwards were
exposed to Si+ at E=1 MeV. The technological procedure included a recovery treatment and for defining the device structure,
the metals were vacuum deposited in order to realize ohmic contacts i.e. PdGeAu/n-GaSb and Ag/p-GaSb. The
characteristics of the sample in different technological stages were investigated by AFM analysis and selective XPS analysis
together with electrical and optical measurements. The result of this experiment was the obtaining of photosensitive structure
with a maximum photo-current response at 1.5μm.

description: We present a conjecture for the crossing symmetry rules for Chern-Simons gauge theories interacting with massive matter in $2+1$ dimensions. Our crossing rules are given in terms of the expectation values of particular tangles of Wilson lines, and reduce to the standard rules at large Chern-Simons level. We present completely explicit results for the special case of two fundamental and two antifundamental insertions in $SU(N)_k$ and $U(N)_k$ theories. These formulae are consistent with the conjectured level-rank, Bose-Fermi duality between these theories and take the form of a $q=e^{\frac{ 2 πi }κ}$ deformation of their large $k$ counterparts. In the 't Hooft large $N$ limit our results reduce to standard rules with one twist: the $S$-matrix in the singlet channel is reduced by the factor $\frac{\sin πλ}{πλ} $ (where $λ$ is the 't Hooft coupling), explaining `anomalous' crossing properties observed in earlier direct large $N$ computations.

description: Study information on the article 'Socioeconomic hardship, uncertainty about the future, and adolescent mental wellbeing over a year during the COVID-19 pandemic'
Abstract | Socioeconomic vulnerabilities put adolescents at risk for mental wellbeing issues, also in times of a pandemic. In the present longitudinal online survey study, we explored changes in mental wellbeing (i.e., mood and life satisfaction) during the COVID-19 pandemic. Second, we examined how socioeconomic hardship in online home schooling predicted adolescents’ mental wellbeing 1 year later. Third, we tested whether this relation was mediated by feelings of uncertainty about the future. Fourth, we tested whether this relation was moderated (in terms of a protective factor) by self-efficacy. In total, 177 Dutch-speaking adolescents aged 10–18 years (Mage = 15.64, SDage = 1.72, 79% females) participated in all three 6-month separated waves (T1 = May 2020, T2 = November 2020, and T3 = May 2021). Mood results demonstrated that feelings of vigor decreased between T1 and T2, and feelings of tension and depression increased between T1, T2, and T3. Socioeconomic hardship in online home schooling in the early phase of the pandemic was negatively associated with both baseline mental wellbeing and 1 year later. Socioeconomic hardship at T1 predicted higher feelings of future uncertainty at T2, and higher levels of future uncertainty were associated with lower feelings of vigor, and higher feelings of tension and depression at T3. However, we found no evidence for mediation or moderation effects. In conclusion, the present findings illustrate the complexity of disentangling the adverse effects of socioeconomic hardship on adolescent mental wellbeing.
High Tc via spin fluctuations from incipient bands: application to monolayers and intercalates of FeSe

description: We investigate superconductivity in a two-band system with an electron- and hole-like band, where one of the bands is away from the Fermi level (or incipient). We argue that the incipient band contributes significantly to spin-fluctuation pairing in the strong coupling limit where the system is close to a magnetic instability, and can lead to a large Tc. In this case, Tc is limited by a competition between the frequency range of the coupling (set by an isolated paramagnon) and the coupling strength itself, such that a dome-like Tc dependence on the incipient band position is obtained. The coupling of electrons to phonons is found to further enhance Tc. The results are discussed in the context of experiments on monolayers and intercalates of FeSe.
