During the last decade, transition metal oxides have been actively investigated as holeand electron-selective materials in organic electronics due to their low-cost processing. In this study, four transition metal oxides (V2O5, MoO3, WO3, and ReO3) with high work functions (>5 eV) were thermally evaporated as front p-type contacts in planar n-type crystalline silicon heterojunction solar cells....

Engineering the interplay of structural degrees freedom that couple to external stimuli such as temperature and pressure is a powerful approach for material design. New expand potential concept, coordination polymers chemically versatile platform offer fascinating possibilities address this challenge. Here, we report new class perovskite-like AB2X6 based on [BX3] ? ReO3-type host network ([Mn(C...

We report the pressure-induced crystallographic transitions and optical behavior of MAPbI3 (MA=methylammonium) using in situ synchrotron X-ray diffraction and laser-excited photoluminescence spectroscopy, supported by density functional theory (DFT) calculations using the hybrid functional B3PW91 with spin-orbit coupling. The tetragonal polymorph determined at ambient pressure transforms to a R...

In this study we have investigated the influence of hydrogen intercalation on the local atomic structure of rhenium trioxide using a new approach to EXAFS data analysis, based on the evolutionary algorithm (EA). The proposed EA-EXAFS method is an extension of the conventional reverse Monte Carlo approach but is computationally more efficient. It allows one to perform accurate analysis of EXAFS ...

The barrier properties and diffusion behavior of Cu(Re) alloy films were studied. deposited onto barrierless SiO2/Si by magnetron sputtering. X-ray diffraction patterns electric resistivity results proved that the without a layer thermally stable up to 550 °C. Transmission electron microscopy images energy-dispersive spectrometry employing scanning transmission provided evidence for self-formed...
