description: Single and multi-band (Burt-Foreman) k.p Hamiltonians for GaAs crystal phase quantum dots are developed and used to assess ongoing experimental activity on the role of such factors as quantum confinement, spontaneous polarization, valence band mixing and exciton Coulomb interaction. Spontaneous polarization is found to be a dominating term. Together with the control of dot thickness [Vainorious Nano Lett. 15, 2652 (2015)] it enables wide exciton wavelength and lifetime tunability. Several new phenomena are predicted for small diameter dots [Loitsch et al. Adv. Mater. 27, 2195 (2015)], including non-heavy hole ground state, strong hole spin admixture and a type-II to type-I exciton transition, which can be used to improve the absorption strength and reduce the radiative lifetime of GaAs polytypes.

description: Accurate forecasting of lithium-ion battery performance is essential for easing consumer concerns about the safety and reliability of electric vehicles. Most research on battery health prognostics focuses on the research and development setting where cells are subjected to the same usage patterns. However, in practical operation, there is great variability in use across cells and cycles, thus making forecasting challenging. To address this challenge, here we propose a combination of electrochemical impedance spectroscopy measurements with probabilistic machine learning methods. Making use of a dataset of 88 commercial lithium-ion coin cells generated via multistage charging and discharging (with currents randomly changed between cycles), we show that future discharge capacities can be predicted with calibrated uncertainties, given the future cycling protocol and a single electrochemical impedance spectroscopy measurement made immediately before charging, and without any knowledge of usage history. The results are robust to cell manufacturer, the distribution of cycling protocols, and temperature. The research outcome also suggests that battery health is better quantified by a multidimensional vector rather than a scalar state of health.

title: The Structural and Magnetic Characterisation of Perovskite-Related Oxyfluoride Materials
Creators: name: Scott, Euan Alexander Sauchin
Publisher: name: University of Kent
Year: 2023

description: This thesis explores two n=1 Aurivillius oxyfluoride phases and their structural characterisation and how this relates to their physical properties. Bi2CoO2F4 was successfully analysed using XRPD, NPD, XANES and SHG techniques. Structural characterisation of NPD data collected at 50 K and at 5 K indicated rotations of CoF6 octahedra about both in-plane and out-of-plane axes, whilst SHG activity supports the assignment of a nocentrosymmetric symmetry. Rietveld refinements suggest a ground state Pca21 symmetry. Low temperature NPD data allowed exploration of the magnetic structure. Analysis indicated the magnetic symmetry was close to a collinear antiferromagnetic structure with in-plane moments;however, two very similar magnetic structures were obtained, one of which has a ferromagnetic component allowed by symmetry, which may explain unusual field dependence found in magnetic susceptibility measurements. Theory work has highlighted the possibility of anion ordering in heteroanionic materials breaking inversion symmetry and so we carry out a symmetry analysis of possible anion-ordered arrangements for Bi2TiO4F2 assuming mer or fac [TiO3F3]units. Although these units are polar, there are 12 ways of arranging these polar units based on an ideal parent model of I4/mmm symmetry, only 4 of these models are non-centrosymmetric and would allow macroscopic polarisation. Interestingly, further analysis has shown that allowing non-polar octahedral rotations in non-polar anion-ordered models can break inversion symmetry, and this represents a new avenue for designing hybrid-improper materials.

description: In this work, we present a method to characterise the transmission matrices of complex scattering media using a physics-informed, multi-plane neural network (MPNN) without the requirement of a known optical reference field. We use this method to accurately measure the transmission matrix of a commercial multi-mode fiber without the problems of output-phase ambiguity and dark spots, leading to upto 58% improvement in focusing efficiency compared with phase-stepping holography. We demonstrate how our method is significantly more noise-robust than phase-stepping holography and show how it can be generalised to characterise a cascade of transmission matrices, allowing one to control the propagation of light between independent scattering media. This work presents an essential tool for accurate light control through complex media, with applications ranging from classical optical networks, biomedical imaging, to quantum information processing.

description: The recent report of near-ambient superconductivity in nitrogen doped lutetium hydride has triggered a worldwide fanaticism and raised major questions about the latest claims. An intriguing phenomenon of color changes in pressurized samples from blue to pink to red was observed and correlated with the claimed superconducting transition, but the origin and underlying physics of these color changes have yet to be elucidated. Here we report synthesis and characterization of high-purity nitrogen doped lutetium hydride LuH$_{2\pm\text{x}}$N$_y$ with the same structure and composition as in the main phase of near-ambient superconductor1. We find a new purple phase of LuH$_{2\pm\text{x}}$N$_y$ between blue and pink phase, and reveal that the sample color changes likely stem from pressure-driven redistribution of nitrogen and its interaction with the LuH$_2$ framework. No superconducting transition is found in all blue, purple, pink and red phases at temperatures 1.8-300 K and pressures 0-30 GPa. Instead, we identify a notable temperature-induced resistance anomaly of structural and/or electronic origin in LuH$_{2\pm\text{x}}$N$_y$, which is most pronounced in the pink phase and may have been erroneously interpreted as a sign of superconducting transition. This work establishes key benchmarks for nitrogen doped lutetium hydrides, allowing an in-depth understanding of the novel pressure-induced phase changes.

description: Context. Near open clusters as Pleiades, Praesepe and Blanco 1 have been extensively studied due to their proximity to the Sun. The Gaia data brings the opportunity to investigate these clusters, since it contains valuable astrometric and photometric information which can be used to update their kinematic and stellar properties. Aims. Our goal is to carry out a star membership study in these nearby open clusters employing an astrometric model with proper motions and an unsupervised clustering machine learning algorithm using positions, proper motions and parallaxes. The star members are selected from the cross-matching between both methods. Methods. We use the Gaia DR3 catalogue to determine star members using two approaches: a classical Bayesian model and the unsupervised machine learning algorithm DBSCAN. For star members we build the radial density profiles, the spatial distributions and compute the King parameters. The ages and metallicities were estimated using the BASE-9 Bayesian software. Results. We identified 958, 744 and 488 star members for the Pleiades, Praesepe and Blanco 1 respectively. We corrected the distances and built the spatial distributions, finding that Praesepe and Blanco 1 have elongated shape structures. The distances, ages and metallicities obtained were consistent with the reported in the literature. Conclusions. We obtained catalogues of star members, updated kinematic and stellar parameters for these open clusters. We found that the proper motions model can find a similar number of members as the unsupervised clustering algorithm does when the cluster population form an overdensity in the vector point diagram. It allows to select an adequate size of the proper motions region to run these methods. Our analysis found stars that are being directed towards the outskirts of the Praesepe and Blanco 1, which exhibit elongated shapes.

description: We discuss the thermal pressures ($n_H T$) in predominantly cold, neutral interstellar gas in the Magellanic Clouds, derived from analyses of the fine-structure excitation of neutral carbon, as seen in high-resolution HST/STIS spectra of seven diverse sight lines in the LMC and SMC. Detailed fits to the line profiles of the absorption from C I, C I*, and C I** yield consistent column densities for the 3--6 C I multiplets detected in each sight line. In the LMC and SMC, $N$(C I$_{\rm tot}$) is consistent with Galactic trends versus $N$(Na I) and $N$(CH), but is slightly lower versus $N$(K I) and $N$(H$_2$). As for $N$(Na I) and $N$(K I), $N$(C I$_{\rm tot}$) is generally significantly lower, for a given $N$(H$_{\rm tot}$), in the LMC and (especially) in the SMC, compared to the local Galactic relationship. For the LMC and SMC components with well determined column densities for C I, C I*, and C I**, the derived thermal pressures are typically factors of a few higher than the values found for most cold, neutral clouds in the Galactic ISM. Such differences are consistent with the predictions of models for clouds in systems (like the LMC and SMC) that are characterized by lower metallicities, lower dust-to-gas ratios, and enhanced radiation fields -- where higher pressures are required for stable cold, neutral clouds. The pressures may be further enhanced by energetic activity (e.g., due to stellar winds, star formation, and/or supernova remnants) in several of the regions probed by these sight lines. Comparisons are made with the C I observed in some quasar absorption-line systems.

description: In this work we present a generalization of the recently developed Hardy-like logical proof of contextuality and of the so-called KCBS contextuality inequality for any qudit of dimension greater than three. Our approach uses compatibility graphs that can only be satisfied by qudits. We find a construction for states and measurements that satisfy these graphs and demonstrate both logical and inequality based contextuality for qudits. Interestingly, the quantum violation of the inequality is constant as dimension increases. We also discuss the issue of imprecision in experimental implementations of contextuality tests and a way of addressing this problem using the notion of ontological faithfulness.

description: As utilization of Photovoltaic Charging Stations (PV-CS) that generate clean electricity from the sun increase,
Dublin Institute of Technology (DIT) adopts this application for accommodating the required charge of small
campus Battery Electric Vehicles (BEVs). This paper presents the virtual simulation of the 10.5 kW Battery
Energy Storage System (BESS) based PV-CS model. Transient System Simulation (TRNSYS) built-in climatic
data and modular structure properties were adopted to replicate the experimentally proposed PV-CS, where
special attention was paid to the electrical measurments and energy flow signals. The objective was set to model
the PV-CS system, formulate an energy managment optimisation and justify the ideal value and or potential range
of the equivalent battery size. The primary assessment for energy management of the charging infrastructure was
performed through the formulation of analytical energy balancing optimization. The energy balancing approach
adopted the Simple Payback Period (SPP) method in order to investigate the acquired positive gains (Gain-1 and
Gain-2) by BESS unit. The key variables for tuning the BESS capacity were load profile and size of BESS. The
resultant measurement signals from TRNSYS were monitored and compared to their analytical equivalents,
where verification and conclusion on accuracy improvements for BESS capacity and reliable system performance
were drawn.

description: High precision and large dynamic range measurement are required in the readout systems for the Water Cherenkov Detector Array (WCDA) in Large High Altitude Air Shower Observatory (LHAASO). This paper presents a prototype of 12-bit 40 MSPS Analog-to-Digital Converter (ADC) Application Specific Integrated Circuit (ASIC) designed for the readout of LHAASO WCDA. Combining this ADC and the front-end ASIC finished in our previous work, high precision charge measurement can be achieved based on the digital peak detection method. This ADC is implemented based on power-efficient Successive Approximation Register (SAR) architecture, which incorporates the key parts such as Capacitive Digital-to-Analog Converter (CDAC), dynamic comparator and asynchronous SAR control logic. The simulation results indicate that the Effective Number Of Bits (ENOB) with a sampling rate of 40 MSPS is better than 10 bits in an input frequency range below 20 MHz, while its core power consumption is 6.6 mW per channel. The above results are good enough for the readout requirements of the WCDA.

description: The accumulation of dust on PV modules surface results in a loss of performance. PV plants installed in
areas prone to pollution, or to the presence of sand or sea salt in the atmosphere are more affected by soiling. The
process is also favored by the scarcity of rainfalls. The South Tyrol region (North-East of Italy) is not particularly
affected by this process. However, in the last two months of 2015 a dry period with no rainfalls was registered in the
area. This coincided with construction works on the extension of the runways at Airport Bolzano Dolomiti, where a
multi-technology PV test facility is installed.
This paper calculates the performance losses, expressed as daily percentage, of 13 crystalline-silicon based PV
technologies. Comparisons are carried out considering different glass textures (smooth vs structured), orientations of
the modules within the array (portrait vs landscape) and the presence of a frame.

production data, GPS coordinates, and global solar irradiation for the site. The model is based on hourly production
data, but could be extended to sub-hourly data. The detection of the shading mask through the production curve itself
allows the operator to anticipate the production curve due to shading – and eliminate shading impacts in failure
detection routines that can then concentrate on component (inverter, string, …) failure, so that operators can responde
appropriately.

description: One of the main degradation mechanisms of the zirconium alloys used in nuclear reactors is hydrogen embrittlement and hydride formation. The formation of zirconium hydrides is accompanied by a transformation strain, the effects of which on the development of localized deformation zones are not well-understood. This study uses a crystal plasticity finite element model that is coupled with diffusion subroutines to quantify such effects. For this purpose, a zirconium specimen was hydrided in the absence of any external mechanical loads. With the use of electron backscatter diffraction, the rotation fields around interacting intragranular hydrides as well as those located at grain boundaries or triple points were measured at a high spatial resolution. The as-measured zirconium and hydride morphologies were mapped to the model for numerical simulation. Both numerical and experimental results show that hydride precipitation induces large rotation fields within the zirconium matrix, where such rotations are at their maximum in the vicinity of hydride tips. While the crystallographic orientations and shapes of hydrides affect the magnitude of rotation fields, both experimental and modeling results revealed the development of discrete and parallel geometrically necessary dislocation fields and a strong interaction among neighboring hydrides. It is shown that the stress field resulting from hydride precipitation affects the patterning of hydrogen distribution, which in return affects further hydride interlinking.

description: The outdoor assessment of photovoltaic (PV) systems provides useful data to validate performance
modelling approaches. The scope of this work is to analyse and model the outdoor performance of different gridconnected
poly-crystalline Silicon (poly-c Si) PV systems installed at the PV Technology Laboratory of the
University of Cyprus (UCY). These systems provided by Hanwha Q CELLS were installed side-by-side at a fixedplane
and monitored for a period of one year. Apart from PV system operational data, meteorological data were also
extracted. Specifically, the focus of this ongoing analysis is to compare the performance of different modelling
methods against real outdoor energy measurements and to investigate the impact of using real meteorological data for
the simulation using the PVWATTS model and the PVSYST simulation software. The annual DC Performance Ratio
(PRDC) results using the PVWATTS model and calculated using the PVSYST software showed that the prediction
error (PE) was below 2 % for the PVSYST simulation, whereas for the PVWATTS model PE differences of up to 8
% were observed when compared to the measured PRDC.

description: As solar panels are being deployed at GW scales across diverse climatic regions, and as the solar industry
must increasingly compete on a leveled cost of energy (LCOE) basis, the effects and cost of soiling on panel output is
becoming more acute. Numerous studies have investigated soiling losses in different locations and under different
climatic conditions. Studies of various anti-soiling coatings have shown that coatings can exhibit an anti-soiling effect
in many locations and applications. However, the data reported typically covers only a single season or just part of a
year. Additionally, it is likely that local effects play a significant role in soiling factors, but the data may lack sufficient
geographic coverage to resolve such local effects. Here, we present an analysis of 3 years of field data collected at 10
locations throughout the Southwestern United States comparing the performance of a durable hydrophobic antireflective
coating to uncoated PV glass. We report on soiling rates over the study period. We conclude that hydrophobic
coatings have a significant anti-soiling effect at most arid sites in relation to the performance of the uncoated glass
controls.

description: We study consistently the effects of magnetic field on hot and dense matter. In particular, we look for differences that arise due to assumptions that reproduce the conditions produced in particle collisions or astrophysical scenarios, such as in the core of fully evolved neutron stars (beyond the protoneutron star stage). We assume the magnetic field to be either constant or follow a profile extracted from general relativity calculations of magnetars and make use of two realistic models that can consistently describe chiral symmetry restoration and deconfinement to quark matter, the Chiral Mean Field (CMF) and the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) models. We find that net isospin, net strangeness, and weak chemical equilibrium with leptons can considerably change the effects of temperature and magnetic fields on particle content and deconfinement in dense matter. We finish by discussing the possibility of experimentally detecting quark deconfinement in dense and/or hot matter and the possible role played by magnetic fields.

description: Hot stars emit large amounts of X-rays, which are assumed to originate in the supersonic stellar wind. Part of the emitted X-rays is subsequently absorbed in the wind and influences its ionization state. Because hot star winds are driven radiatively, the modified ionization equilibrium affects the radiative force. We review the recent progress in modelling the influence of X-rays on the radiative equilibrium and on the radiative force. We focus particularly on single stars with X-rays produced in wind shocks and on binaries with massive components, which belong to the most luminous objects in X-rays.

description: We demonstrate optomechanical quantum control of the internal electronic states of a diamond nitrogen vacancy (NV) center in the resolved-sideband regime by coupling the NV to both optical fields and surface acoustic waves via a phonon-assisted optical transition and by taking advantage of the strong excited-state electron-phonon coupling of a NV center. Optomechanically-driven Rabi oscillations as well as quantum interferences between the optomechanical sideband and the direct dipole-optical transitions have been realized. These studies open the door to using resolved-sideband optomechanical coupling for quantum control of both the atom-like internal states and the motional states of a coupled NV-nanomechanical system, leading to the development of a solid-state analog of trapped ions.

description: Output power of a residential PV system is reduced by many factors such as shading, a malfunction, and a
breakdown. A remote diagnoses method for residential PV systems by using Operating Performance Index (OPI) is
developed in this research. OPI is defined as measured power generation divided by estimated power generation. In order
to vilify the effect of time resolution on accuracy of OPI calculation, OPI(t) was calculated in the following measurement
intervals: 1, 5, 10, 30, and 60 min. We also divided the celestial sphere into the following azimuth  [deg.] and solar height
h [deg.] resolutions:  = 5, 10, 15, and 20, h =5, 10, and 15. OPIm(,h) is the OPI(t) frequency value of each sector of
and h. OPIMp is the mode value of OPIm(,h) and it shows power generation performance of the system. We have evaluated
OPI at different measurement intervals with various celestial sphere resolutions.

description: Monitoring the performance of PV installations can be very labour intensive. The efficiency can
significantly be increased by using a thermal imaging drone system. The Photovoltaic Laboratory (PV LAB) at Bern
University of Applied Sciences BFH in Burgdorf, Switzerland, hence developed and built its own thermal imaging
drone. Drone-based inspection of several Swiss PV installations operated by the PV LAB was conducted and
degradation (kG) factors were calculated. Comparison of the kG-factors evidenced that cleaning the PV module
surfaces may increase the energy yield production up to 9%. The drone-based thermal images offered a real
advantage for the detection of “hot spots” in PV modules and associated differences in solar cell temperatures,
indicating power decreases. However, the quantification of extra energy yields gained from cleaning homogeneous
environmental pollution on PV module surfaces needs to be based on measurements.

description: The ongoing growth of renewable energy installations is slowly shifting the energy mix for grids
worldwide. Photovoltaic (PV) installations in specific have increased their share and PV currently covers more than
6% of the peak electricity demand in Europe. These growing numbers give hope for a sustainable future but also
showcase the increasing challenges that the PV industry will have to face. With such a big number of PV installations
on the grid, each with different size and characteristics, it is crucial to develop tools and methods for efficient
monitoring and problem detection. The kind of dynamism, which occurs in time scales much shorter than 1 hour,
requires PV models that inherently incorporate the dynamic effects of the PV system, like thermal transients and
response time constants, also scalable both spatially and temporally. State of the art parametric models are unsuitable
for fine time resolutions or non-uniform environmental conditions. In this work a novel PV model is presented,
suitable for non-uniform, fast varying conditions on small time scales, for online monitoring and control of the PV
plant. The model is validated on a 62.5 kWp installation for a period of 4 months and retains a root-mean-square
(RMS) error of less than 5% even for time periods down to 10 seconds.

is possible to simulate tracking and backtracking of 3D solar components with one or two axis in any plane, and to

description: We report the results of the first long-term (1990-2014) optical spectro-photometric monitoring of a binary black hole candidate QSO E1821+643, a low-redshift high-luminosity radio-quiet quasar. In the monitored period the continua and H$γ$ fluxes changed for around two times, while the H$β$ flux changed around 1.4 times. We found the periodical variations in the photometric flux with the periods of 1200, 1850 and 4000 days, and 4500 days periodicity in the spectroscopic variations. However, the periodicity of 4000-4500 days covers only one cycle of variation and should be confirmed with a longer monitoring campaign. There is an indication of the period around 1300 days in the spectroscopic light curves, but with small significance level, while the 1850 days period could not be clearly identified in the spectroscopic light curves. The line profiles have not significantly changed, showing an important red asymmetry and broad line peak redshifted around +1000 km s$^{-1}$. However, H$β$ shows broader mean profile and has a larger time-lag ($τ\sim120$ days) than H$γ$ ($τ\sim60$ days). We estimate that the mass of the black hole is $\sim2.6\times10^9\rm M_\odot$. The obtained results are discussed in the frame of the binary black hole hypothesis. To explain the periodicity in the flux variability and high redshift of broad lines we discuss a scenario where dense gas-rich cloudy-like structures are orbiting around a recoiling black hole.

description: We say that $G$ is a $(3, 3)$-Ramsey graph if every $2$-coloring of the edges of $G$ forces a monochromatic triangle. The $(3, 3)$-Ramsey graph $G$ is minimal if $G$ does not contain a proper $(3, 3)$-Ramsey subgraph. In this work we find all minimal $(3, 3)$-Ramsey graphs with up to 13 vertices with the help of a computer, and we obtain some new results for these graphs. We also obtain new upper bounds on the independence number and new lower bounds on the minimum degree of arbitrary $(3, 3)$-Ramsey graphs.

description: Understanding protein-protein interactions is central to our understanding of almost all complex biological processes. Computational tools exploiting rapidly growing genomic databases to characterize protein-protein interactions are urgently needed. Such methods should connect multiple scales from evolutionary conserved interactions between families of homologous proteins, over the identification of specifically interacting proteins in the case of multiple paralogs inside a species, down to the prediction of residues being in physical contact across interaction interfaces. Statistical inference methods detecting residue-residue coevolution have recently triggered considerable progress in using sequence data for quaternary protein structure prediction; they require, however, large joint alignments of homologous protein pairs known to interact. The generation of such alignments is a complex computational task on its own; application of coevolutionary modeling has in turn been restricted to proteins without paralogs, or to bacterial systems with the corresponding coding genes being co-localized in operons. Here we show that the Direct-Coupling Analysis of residue coevolution can be extended to connect the different scales, and simultaneously to match interacting paralogs, to identify inter-protein residue-residue contacts and to discriminate interacting from noninteracting families in a multiprotein system. Our results extend the potential applications of coevolutionary analysis far beyond cases treatable so far.

description: We construct a covariant generating function for the spectrum of chiral primaries of symmetric orbifold conformal field theories with N=(4,4) supersymmetry in two dimensions. For seed target spaces K3 and T4, the generating functions capture the SO(21) and SO(5) representation theoretic content of the chiral ring respectively. Via string dualities, we relate the transformation properties of the chiral ring under these isometries of the moduli space to the Lorentz covariance of perturbative string partition functions in flat space.

description: In this paper we report on the high stability of our n-type front junction solar cells (n-PERT) exposed
to potential-induced degradation (PID) and UV-induced degradation (UVID) conditions. These intrinsically stable n-
Pasha cells enable PID- and UVID-free modules even with industrially low-cost standard EVA encapsulant,
independent of system grounding and system voltage. Based on intentional modifications of the Boron emitter and/or
the dielectric layer in the PID-free and UVID-free n-Pasha solar cells, we are able to replicate reported degradation
effects and study the mechanisms behind it. A combination of altering the boron profile and the dielectric properties
together with increasing the interface defect density Dit is detrimental for the stability. Applying our standard optimal
B-diffusion and passivation scheme assure that the UV radiation and system voltage have virtually no effect on our n-
Pasha cell and module performance.

description: Business process models abstract complex business processes by representing them as graphical models. Their layout, solely determined by the modeler, affects their understandability. To support the construction of understandable models it would be beneficial to systematically study this effect. However, this requires a basic set of measurable key visual features, depicting the layout properties that are meaningful to the human user. The aim of this research is thus twofold. First, to empirically identify key visual features of business process models which are perceived as meaningful to the user. Second, to show how such features can be quantified into computational metrics, which are applicable to business process models. We focus on one particular feature, consistency of flow direction, and show the challenges that arise when transforming it into a precise metric. We propose three different metrics addressing these challenges, each following a different view of flow consistency. We then report the results of an empirical evaluation, which indicates which metric is more effective in predicting the human perception of this feature. Moreover, two other automatic evaluations describing the performance and the computational capabilities of our metrics are reported as well.

description: Development of extended accelerated test protocols that don’t introduce superfluous failure modes is
necessary to understand long term PV module durability. Extended Damp Heat (DH) testing beyond 2000 hours is
often performed to understand long term durability of PV modules. However, such type of harsh testing is known to
introduce failure modes not seen in field. This work describes a non-traditional approach taken by JSEC which
combines DH and outdoor exposure in Florida. Modules procured from market from 3 different manufacturers having
glass-EVA-backsheet design were used in this study. The modules were first passed through DH testing for 1000,
1500 and 2000 hours for 3 manufacturers respectively. Consequently, the modules were deployed on a rooftop array
in Florida for 4 years. Module characterization including Electroluminescence (EL) and flash I-V was performed
initially, after DH exposure and after outdoor exposure to understand failure mechanism. It was deduced that acetic
acid formed during DH exposure accelerated the corrosion of silver grid with the availability of heat, humidity and
UV during outdoor exposure. However, the presence of cell cracks mitigated the corrosion in the local areas as acetic
acid formed at the front of the cell could escape through backsheet.

description: Separating the influence of hyperfine from spin-orbit interactions in spin-dependent carrier recombination and dissociation processes necessitates magnetic resonance spectroscopy over a wide range of frequencies. We have designed compact and versatile coplanar waveguide resonators for continuous-wave electrically detected magnetic resonance, and tested these on organic light-emitting diodes. By exploiting both the fundamental and higher-harmonic modes of the resonators we cover almost five octaves in resonance frequency within a single setup. The measurements with a common pi-conjugated polymer as the active material reveal small but non-negligible effects of spin-orbit interactions, which give rise to a broadening of the magnetic resonance spectrum with increasing frequency.
