Minimum output entropy of a non-Gaussian quantum channel
Creators: name: Memarzadeh, Laleh

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce a model of non-Gaussian quantum channel that stems from the combination of two physically relevant processes occurring in open quantum systems, namely amplitude damping and dephasing. For it we find input states approaching zero output entropy, while respecting the input energy constraint. These states fully exploit the infinite dimensionality of the Hilbert space. Upon truncation of the latter, the minimum output entropy remains finite and optimal input states for such a case are conjectured thanks to numerical evidences.

description: Due to a different surface concentration and type of minority charge carriers compared to n+ emitters
(on p-type substrates), novel surface passivation methods are required when using p+ emitters on n-type silicon for
which a number of efficiency records have been achieved in recent years [1,2,3]. In this study emitter saturation
current densities j0e of two BBr3 diffused emitters passivated by a variety of dielectric stacks are compared using
following processes: SiOx by dry thermal oxidation, direct and remote plasma enhanced chemical vapor deposited
SiNx, atomic layer deposited Al2O3, SiOx remaining from the RCA standard cleaning process [4] yielding the lowest
j0e of 17.5 fA/cm² for a sample passivated by an Al2O3/SiNx stack. Furthermore, the j0BSF values of POCl3 diffused n+
surfaces passivated by several passivation layers are determined as they are applied at the solar cell rear side. The
resulting combined j0e and j0BSF values j0combined are compared with IV characteristics of solar cells passivated by the
corresponding passivation of emitter and BSF on front- and rear side. As passivation layers are additionally employed
as antireflection coatings also the spectral reflectance of the investigated passivation stacks with optimized thickness
was determined.

description: The $^{10}$B(p,$α$)$^{7}$Be reaction is of great interest since it has many applications in different fields of research such as nuclear astrophysics, nuclear physics, and models of new reactors for clean energy generation. This reaction has been studied at the AN2000 accelerator of the INFN National Laboratories of Legnaro (LNL). The total cross section has been measured in a wide energy range (250 $-$ 1182 keV) by using the activation method. The decays of the $^7$Be nuclei produced by the reaction were measured at the low counting facility of LNL by using two fully shielded high-purity germanium detectors. The present dataset shows a large discrepancy with respect to one of the previous data at the same energies and reduces the total uncertainty to the level of 6\%. An R-matrix calculation has been performed on the present data using the parameters from previous Trojan Horse measurements for the 10 and 500 keV resonances. The present data do not lay on the R-matrix fit in one point suggesting the existence of a $^{11}$C level not observed yet. Further nuclear investigations are needed to confirm this hypothesis.

description: In front contact metallization of solar cells, fine line contacts with high aspect ratio help to reduce both
shading loss and finger resistive loss. It also helps in reducing the recombination loss at the metal-semiconductor
interface due to reduction in contact area. Using low cost nickel-copper based electroplating technique, contacts with
better aspect ratio can be grown compared to state of the art screen printing technique. Additionally, copper is being
considered as a replacement material for silver based paste in screen printing technology due to much lower cost and
higher line conductivity. In this work, direct laser patterning of silicon nitride and nickel-copper based metallization
have been applied to get fine line front contacts with high aspect ratio. The effect of process parameters related to
direct laser patterning and nickel-copper metallization on aspect ratio is also studied. It is found that there is
significant dependence of aspect ratio on substrate morphology, seed layer width and electroplating duration or
contact thickness. Uniform and continuous nickel seed layer formation only on the laser patterned area is crucial for
subsequent copper electroplating. The final copper line width and aspect ratio is highly dependent on the continuity
and width of the nickel seed layer. Nickel seed layer was deposited using electroless chemical bath deposition process
with PdCl2 activation and annealed at 420 °C for 60s for making it ohmic contact by silicidation process.
Subsequently copper electroplating was done to enhance the line conductivity. Electroplating duration was varied to
achieve different copper finger line thicknesses which resulted in variation of aspect ratio in the range of 0.1 – 0.5.
Fine Cu-electroplated contacts with good line contrast have been obtained. A minimum of 22 μm final Cuelectroplated
finger width has been obtained with aspect ratio of 0.48 and contact thickness of 10.63 μm. Aspect ratio
beyond this value is also achievable by fine line continuous seed layer deposition and improvement in Cuelectroplating
process.

description: Screen printing for metallisation of conventional silicon wafer solar cells typically includes a hightemperature
(~800 °C) firing step for contact formation to heavily doped silicon regions. However, amorphous/
crystalline silicon (a-Si:H/c-Si) heterojunction (HET) solar cells have two unique metallisation requirements: (1) the
metal needs to contact a transparent conductive oxide layer and (2) the annealing step for contact formation/metal
sintering needs to be restricted to moderate temperatures (typically ≤ 200 °C) to avoid degradation of the cell’s thin
a-Si layers. Screen printing using silver based polymer pastes can meet these requirements. In this paper, we present a
detailed characterisation of three silver based polymer pastes (PV412, L9281 and L9282 from DuPont) in terms of
contact formation to aluminium doped zinc oxide (AZO) layers and the annealing behaviour of the pastes. Average
specific contact resistance for all three pastes on AZO is measured to be in the range 3 to 5 mΩ.cm2. The sheet
resistance of printed fingers for L9281 and L9282 is measured to be ~5 mΩ/sq for typical single prints after annealing
in air at 200 °C for 60 minutes. Based on our results both L9281 and L9282 appear to be promising candidates for
HET metallisation.

description: In this work we demonstrate that the tin plating performed on screen-printed Al contact is able both to
produce suitable contact with Al-Si and to replace the silver from the back contact in the cell manufacturing process
thus reducing the solar cell cost. To this aim we have developed an innovative technique based on dynamic liquid
meniscus able to touch the cell back contact in specific defined positions and perform wet processing such as Tin
plating. We have used high resolution Scanning Electron Microscopy (SEM) and compositional microanalysis with
Energy Dispersive X-Ray microanalysis (EDX) to evaluate the tin dispersion within aluminum-silicon interdiffused
region and Transfer Length Method and current-voltage measurements to estimate the specific contact resistivity of
the Sn-Al/c-Si metal contact and series resistance of the overall solar cell device. Several commercial aluminum
screen printable pastes have been experimented also having different distribution of sphere particles dimensions. We
have found that the interconnection ribbon soldered on tin contacts plated on screen printed aluminum back contact
shows adhesion higher (> 1N/mm) than that verified on screen printed silver over silicon.

description: The past decade witnessed the observation of several exotic charmonium-like resonances, some of which are manifestly non-qqbar mesons. We review one of the most popular interpretations of such states: the compact tetraquark in the constituent diquark-antidiquark picture. Moreover, we discuss some unexplored decay channels which are particularly sensitive to the different phenomenological models and could therefore shed some light on the nature of these fascinating states. Some brief comments on the recently observed pentaquarks are also included.

description: The high density of evanescent modes in the vicinity of a metal leads to enhancement of the near-field Förster resonant energy transfer (FRET) rate. We present a classical approach to calculate the FRET rate based on the dyadic Green's function of an arbitrary dielectric environment, and consider non-local limit of material permittivity in case of metallic halfspace and thin film. In a dimer system, we find that the FRET rate is enhanced due to shared evanescent photon modes bridging a donor and an acceptor. Furthermore, a general expression for the FRET rate for multimer systems is derived. The presence of a dielectric environment and the path interference effect enhance the transfer rate, depending on the combination of distance and geometry.

wafer before and after textured in KOH/IPA solution are presented and antireflection properties are studied. A
considerable suppression of the reflection less than 2.5 % in a broad spectral range (300–1100 nm) is observed in
nano-textured samples. The nickel catalyzed electroless nano-texturing in aqueous HF and H2O2 solution at room
temperature is demonstrated as a simple, fast and low cost process, to realize effective low reflective silicon surface
which has potential for silicon solar cells applications. The optical properties and morphology of nanostructured
surface are presented and discussed in correlation with the noble metal assisted etching.

description: Distributed software is becoming more and more dynamic to support applications able to respond and adapt to the changes of their execution environment. For instance, service-oriented computing (SOC) envisages applications as services running over globally available computational resources where discovery and binding between them is transparently performed by a middleware. Asynchronous Relational Networks (ARNs) is a well-known formal orchestration model, based on hypergraphs, for the description of service-oriented software artefacts. Choreography and orchestration are the two main design principles for the development of distributed software. In this work, we propose Communicating Relational Networks (CRNs), which is a variant of ARNs, but relies on choreographies for the characterisation of the communicational aspects of a software artefact, and for making their automated analysis more efficient.

description: This paper reviews our recent progress in the development of metal wrap through (MWT) cells and
modules, produced from n-type Czochralski silicon wafers. The use of n-type silicon as base material allows for high
efficiencies: for front emitter-contacted industrial cells, efficiencies above 20% have been reported. N-type MWT (n-
MWT) cells produced by industrial process technologies allow even higher efficiency due to reduced front metal
coverage. Based on the same industrial technology, the efficiency of the bifacial n-MWT cells exceeds the efficiency of
the n-type front-and-rear contact and bifacial “Pasha” technology (n-Pasha) by 0.1-0.2% absolute, with a maximum n-
MWT efficiency of 20.1% so far.
Additionally, full back-contacting of the MWT cells in a module results in reduced cell to module (CTM) fill factor
losses. In a direct 60-cell module performance comparison, the n-MWT module, based on integrated backfoil, produced
3% higher power output than the comparable tabbed front emitter-contacted n-Pasha module. Thanks to reduced resistive
losses in copper circuitry on the backfoil compared to traditional tabs, the CTM FF loss of the MWT module was reduced
by about 2.2%abs. compared to the tabbed front emitter contact module. A full-size module made using MWT cells of
19.6% average efficiency resulted in a power output close to 280W.
Latest results of the development of the n-MWT technology at cell and module level are discussed in this paper,
including a recent direct comparison run between n-MWT and n-Pasha cells and results of n-MWT cells from 140μm
thin mono-crystalline wafers, with only very slight loss (1% of Isc) for the thin cells. Also reverse characteristics and
effects of reverse bias for extended time at cell and module level are reported, where we find a higher tolerance of MWT
modules than tabbed front contact modules for hotspots.

description: Different cleaning solutions have been investigated on their performance as pre-diffusion and prepassivation
cleans for p-type cz-silicon wafers and their potential for application in a high efficiency industrial PERC
manufacturing flow [1]. Candidates like SC1 and Seluris® C were benchmarked against an industrial HCl/HF low
cost clean and a high end CMOS SPM+HCl/HF clean. After applying the different cleaning solutions at different
temperatures and with varied final surface polarity, the silicon surface is passivated by a dielectric stack of
AlOx/SiOx/SiNx [2]. It was shown that, independent on temperature, hydrophobic ending flows are superior to
hydrophilic cleans and that a both SC1/HF and a simple clean like HCl/HF did not achieve the high lifetime value
and cell efficiency of more sophisticated cleans. Metal contamination tests indicate that high bath stability and metal
attracting capacity of a sophisticated cleaning approach may become a preferred choice not only because of cleaning
performance, but also regarding long bath lifetimes and thus cost of ownership considerations.

description: We address adaptive radar detection of targets embedded in ground clutter dominated environments characterized by a symmetrically structured power spectral density. At the design stage, we leverage on the spectrum symmetry for the interference to come up with decision schemes capable of capitalizing the a-priori information on the covariance structure. To this end, we prove that the detection problem at hand can be formulated in terms of real variables and, then, we apply design procedures relying on the GLRT, the Rao test, and the Wald test. Specifically, the estimates of the unknown parameters under the target presence hypothesis are obtained through an iterative optimization algorithm whose convergence and quality guarantee is thoroughly proved. The performance analysis, both on simulated and on real radar data, confirms the superiority of the considered architectures over their conventional counterparts which do not take advantage of the clutter spectral symmetry.

description: A feasible approach for producing high efficient solar cells is using the local back contact technology.
Thereby the rear side is passivated by a dielectrical layer which is locally opened by laser ablation. All subsequent
process steps are similar to Al-BSF cells. Although a reliable formation of local contacts is more challenging this
technology offers improvements in process stability and consumables. In contrast to an Al-BSF, all processed iPERC
(industrial Passivated Emitter Rear Cell) solar cells show a reduced correlation between applied aluminum weight
and Voc. Experimental data reveal a significant different behavior of iPERC cells (I-V-data, aluminum sheet
resistance, bow, SEM images) dependent on Al thickness as well as peak temperature in the CAMiNI® firing furnace
of Roth & Rau. Presented interrelation between printed aluminum thickness and I-V-cell data offers potential in
lowering costs with higher cell efficiency.

description: Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving the problem. A major focus while helping introductory physics students learn problem solving is to help them appreciate that drawing diagrams facilitates problem solution. We conducted an investigation in which 118 students in an algebra-based introductory physics course were subjected to two different interventions during the problem solving in recitation quizzes throughout the semester. Here, we discuss the problem solving performance of students in different intervention groups for two problems involving standing waves in tubes, one which was given in a quiz and the other in a midterm exam. These problems can be solved using two different methods, one involving a diagrammatic representation and the other involving mostly mathematical manipulation of equations. In the quiz, students were either (1) asked to solve the problem in which a partial diagram was provided or (2) explicitly asked to draw a diagram. A comparison group was not given any instruction regarding diagrams. Students in group (1), who were given the partial diagram, could not use that partial diagram by itself to solve the problem. The partial diagram was simply intended as a hint for students to complete the diagram and follow the diagrammatic approach. However, we find an opposite effect, namely, that students given this diagram were less likely to draw productive diagrams and performed worse than students in the other groups. Moreover, we find that students who drew a productive diagram performed better than those who did not draw a productive diagram even if they primarily used a mathematical approach. Interviews with individual students who were asked to solve the problem provided further insight.

description: In this paper we introduce a new crystalline silicon (c-Si) solar cell fabrication technology based on the
laser processing of dielectric films to create all the highly-doped regions. We call it DopLaCell (Doped by Laser Cell)
structure. The resulting fabrication process can be simplified to just four steps: wafer cleaning, film depositions, laser
processing and metallization. We used phosphorus-doped silicon carbide stacks (SiCx(n)) and aluminium oxide/silicon
carbide (Al2O3/SiCx) stacks for the creation of n+ and p+ regions respectively. As a proof of concept, 1x1 cm2 solar cells
were fabricated on 0.45 Wcm p-type substrates with promising results. The main feature of DopLaCell structure is the
location of the emitter at the rear surface consisting of a point-like laser processed n+ regions combined with an induced
inversion layer in between based on the fixed charge density of the SiCx(n) stacks. Solar cells with distance between rear
emitter regions or pitch ranging from 200 to 350 μm are characterized resulting in a strong decrease of Fill Factor (FF)
from 75.4 to 59.7 %. Suns-Voc measurements show excellent pseudo-FF (p-FF) values beyond 81% in all devices
demonstrating the high quality of laser doping process and the actual limitation of FF by ohmic losses. Device modelling
through 3D simulations demonstrates that these ohmic losses are related to the high sheet resistance of the inversion layer
induced in-between n+ regions. We conclude that there is room for improvement to fully develop the potential of this new
structure, particularly for low resistivity n-type substrates where the high fixed charge densities of Al2O3 can help to
improve FF.

description: SiNx/SiO2 stack film is widely used as antireflective and passivation coating for high efficiency solar
cells. In this paper, optical admittance matrix is used to systemically investigate the antireflective effect of SiNx/SiO2
stack film based on mathematical software MATLAB. In the past, AM1.5G spectrum was rarely used in the
reflection simulation. Meanwhile, most papers were only focused on the stack reflection, the amount of photons
transferring through the stack were not their concerns. Here, the four important parameters of reflectivity curves
distribution, weighted reflectivity, AM1.5G photon flux spectrum and the amount of photon output from the stack are
simultaneously considered in the calculation. The result shows that the optimized thickness combination of
SiNx/SiO2 stack film is 70 nm and 20 nm respectively, and the photon output from the stack can reach the top,
2.618×1017 (1/s·cm2). The verifying experiments were also taken. The best combination appears at SiNx/SiO2 (68
nm/18 nm), which is agree with the theoretical results. Meanwhile, this stack can provide a perfect passivation. The
minority lifetime for a p-type wafer with phosphorus emitter passivated by SiNx/SiO2 (68 nm/18 nm) stack on both
front and rear sides has reached 116.8μs using inline oxidation and inline PECVD SiNx deposition.

description: Within this work an intensive study concerning the electrical insulation of dielectric passivation layers
is carried out. Therefore, metal-insulator-semiconductor (MIS) structures are manufactured. By using a 4-point
measurement setup with ultra-sensitive piko-ampere meters, shunt resistances of the insulation layers and stacks
within these MIS-structures are determined. Most promising is the combination of atomic layer deposited (ALD)
aluminum oxide (Al2O3) with a thickness of 20 nm and plasma enhanced chemical vapor deposited (PECVD) silicon
oxide (SiOx) with a thickness of 1500 nm. These layers allow for median shunt resistances higher than 30 Mcm2
and a complete electrical insulation of wafers with an edge length of 156 mm. It is shown that the layer thickness of
both, Al2O3 and SiOx, have a significant impact on the insulation properties of the whole stack. Defects in insulation
layers which are short-circuited by the metallization are made visible by infra red (IR) measurements.

description: In this work we present the last results of new texturing on hybrid mono-like and
multicrystalline wafers using a combination of alkaline saw damage etch followed by plasma
texturing. The plasma texturing does not depend on the crystal orientation and the aesthetic
of the final cell is good [2].
Then the plasma texturing is done on one face a new batch type reactor (3000 wafers/hour)
with optimized gas utilization.
Finally the cost of this new process is lower compared to acidic industrial wet texturing. A
comparison of this plasma texturing with acidic texturing shows an improvement of short
current density (Jsc) without degradation of the open circuit voltage (Voc). An absolute
efficiency gain of 0.2% and 0.32% were demonstrated respectively on 6 inch mono-like
hybrid and on multicrystalline wafers.

description: Weak G-band (wGb) stars are very peculiar red giants almost devoided of carbon and often mildly enriched in lithium. Despite their very puzzling abundance patterns, very few detailed spectroscopic studies existed up to a few years ago, preventing any clear understanding of the wGb phenomenon. We recently proposed the first consistent analysis of published data for 28 wGb stars and identified them as descendants of early A-type to late B-type stars, without being able to conclude on their evolutionary status or the origin of their peculiar abundance pattern. We used newly obtained high-resolution and high SNR spectra for 19 wGb stars in the southern and northern hemisphere to homogeneously derive their fundamental parameters, metallicities, as well as the spectroscopic abundances for Li, C, N, O, Na, Sr, and Ba. We also computed dedicated stellar evolution models that we used to determine the masses and to investigate the evolutionary status and chemical history of the stars in our sample. We confirm that the wGb stars are stars in the mass range 3.2 to 4.2 M$_\odot$. We suggest that a large fraction could be mildly evolved stars on the SGB currently undergoing the 1st DUP, while a smaller number of stars are more probably in the core He burning phase at the clump. After analysing their abundance pattern, we confirm their strong N enrichment anti-correlated with large C depletion, characteristic of material fully processed through the CNO cycle to an extent not known in other evolved intermediate-mass stars. However, we demonstrate here that such a pattern is very unlikely due to self-enrichment. In the light of the current observational constraints, no solid self-consistent pollution scenario can be presented either, leaving the wGb puzzle largely unsolved.

description: Programming systems incorporating aspects of functional programming, e.g., higher-order functions, are becoming increasingly popular for large-scale distributed programming. New frameworks such as Apache Spark leverage functional techniques to provide high-level, declarative APIs for in-memory data analytics, often outperforming traditional "big data" frameworks like Hadoop MapReduce. However, widely-used programming models remain rather ad-hoc; aspects such as implementation trade-offs, static typing, and semantics are not yet well-understood. We present a new asynchronous programming model that has at its core several principles facilitating functional processing of distributed data. The emphasis of our model is on simplicity, performance, and expressiveness. The primary means of communication is by passing functions (closures) to distributed, immutable data. To ensure safe and efficient distribution of closures, our model leverages both syntactic and type-based restrictions. We report on a prototype implementation in Scala. Finally, we present preliminary experimental results evaluating the performance impact of a static, type-based optimization of serialization.

description: Ultimately, high efficiency solar cells necessitate a high passivation quality of all surfaces and
interfaces. It is known from literature that passivated contacts increase the open circuit voltage by using a tunneling
mechanism through a thin insulating layer. In comparison to these concepts we use a bi-layer of intrinsic and
phosphorous doped amorphous Si as passivation and tunneling layer. In this paper, we are presenting the successful
implementation of an industrially feasible process sequence including a passivation and contacting coating by using
conventional PECVD and PVD processes. The most favorable i-/n+-a-Si:H and Al PVD deposition conditions were
identified. Surprisingly, our experiments showed no clear dependence of the phosphine flow to the passivation
quality. However, only the structures with the highest n-type doping of the doped a-Si:H layer results in contact
resistivity below 10 mΩcm2. Photoluminescence images show a drop by half of the PL count intensity after the Al
metallization. This indicates that the passivation property of the amorphous silicon is mostly retained.

description: In this work a solderable and temperature-stable rear metallization based on physical vapour deposition
(PVD) is developed. A common Al metallization is complemented by a solder stack that consists of a sputter
deposited TiN barrier layer and a thin solderable top layer, which are deposited on an industrial PVD machine in one
process sequence. Peel-tests confirm sufficient adhesion for conventionally soldered cell interconnectors even when
annealing at 425°C for 18 minutes before soldering, as well as stability of the solder joint during thermal aging at
130°C for 85 h. Our results suggest that our Al based PVD metallization scheme is industrially-feasible, compatible
with a common soldering and interconnection process, potentially cost-efficient and therefore suitable for industrial
PERC and other silicon solar cells.

description: The growing world energy consumption, with reliance on conventional energy sources and the associated environmental pollution, are considered the most serious threats faced by man-kind. Heterogeneous photocatalysis has become one of the most frequently investigated technolo-gies, due to its dual functionality, i.e., environmental remediation and converting solar energy into chemical energy, especially molecular hydrogen. H2 burns cleanly and has the highest gravimetric gross calorific value among all fuels. However, the use of a suitable electron donor, in what so-called “photocatalytic reforming”, is required to achieve acceptable efficiency. This oxidation half-reaction can be exploited to oxidize the dissolved organic pollutants, thus, simultaneously improving the water quality. Such pollutants would replace other potentially costly electron donors, achieving the dual-functionality purpose. Since the aromatic compounds are widely spread in the environment, they are considered attractive targets to apply this technology. In this review, different aspects are highlighted, including the employing of different polymorphs of pristine titanium dioxide as pho-tocatalysts in the photocatalytic processes, also improving the photocatalytic activity of TiO2 by loading different types of metal co-catalysts, especially platinum nanoparticles, and comparing the effect of various loading methods of such metal co-catalysts. Finally, the photocatalytic reforming of aromatic compounds employing TiO2-based semiconductors is presented.
