Investigation of Single Atom Catalysts by X‐Ray Absorption Spectroscopy

open access: yesphysica status solidi (a), EarlyView.
X‐ray absorption spectroscopy allows detailed and precise structure determination for single‐atom catalysts, containing transition metal elements at low concentrations. A close correlation to catalytic measurements supports tailored developments of catalyst materials.

Modeling the Optical Efficiency of AlGaN/GaN Light Emission Diodes with 2D Carrier Localization

open access: yesphysica status solidi (a), EarlyView.
A theoretical model is presented to describe the wavelength dependence of the optical efficiency of AlxGa1‐xN/AlN quantum wells and quantum dots emitting deep ultraviolet light between 210 and 310 nm. The model includes hole state symmetry changes, built‐in strain, quantum confinement, and electron–hole localization due to alloy disorder, treated as a ...

Interfacial Chemistry of Cu(In,Ga)S2 on GaP/Si: Insights for Tandem Solar Cell Design

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
This article exposes an in‐depth analysis of the chemical interaction between Cu(In,Ga)S2 thin‐film and GaP/Si(001) pseudo‐substrate, in the framework of the development of high‐efficiency tandem solar cells on Si. A rich Cu‐Ga‐P‐S chemistry at the Cu(In,Ga)S2/GaP interface is uncovered, in the case of Cu(In,Ga)S2 films grown in Cu‐excess conditions ...
