Discovery of new boron-rich chalcogenides: orthorhombic B6X (X=S, Se)
(Scientific Reports, 2020)
New boron-rich sulfde B6S and selenide B6Se have been discovered by combination of high pressure
– high temperature synthesis and ab initio evolutionary crystal structure prediction, and studied by
synchrotron X-ray ...
Low temperature X-ray absorption spectroscopy study of CuMoO4 and CuMo0.90W0.10O4 using reverse Monte-Carlo method
(Elsevier Ltd, 2019)
Reversible thermochromic phase transition between α- and γ-phases was studied in CuMoO4 and CuMo0.90W0.10O4 using X-ray absorption spectroscopy in the temperature range of 10–300 K. Reverse Monte Carlo modelling with ...
Interpretation of the Cu K-edge EXAFS spectra of Cu3N using ab initio molecular dynamics
(Elsevier Ltd, 2020)
Cubic copper nitride (Cu3N) has anti-perovskite structure, and its properties are strongly affected by anisotropic thermal vibrations of copper atoms. Ab initio molecular dynamics (AIMD) simulations were performed in the ...
Influence of Nb-doping on the local structure and thermoelectric properties of transparent TiO2:Nb thin films
(Elsevier Ltd, 2020)
Transparent n-type niobium-doped titanium dioxide thin films (TiO2:1.5 at.%Nb) with pronounced thermoelectric properties were produced from a composite Ti:Nb target by reactive magnetron sputtering. The thin films were ...
Treatment of disorder effects in X-ray absorption spectra beyond the conventional approach
(Elsevier Ltd., 2020)
The contribution of static and thermal disorder is one of the largest challenges for the accurate determination of the atomic structure from the extended X-ray absorption fine structure (EXAFS). Although there are a number ...
Probing the Thermochromic Phase Transition in CuMoO4 by EXAFS Spectroscopy
(Wiley-VCH Verlag, 2018)
Extended X-ray absorption fine structure (EXAFS) spectroscopy at the Mo K-edge is used to follow the thermochromic γ-to-α phase transition in copper molybdate (CuMoO4). The temperature dependence (10–300 K) of the radial ...
X-ray absorption near edge spectroscopy of thermochromic phase transition in CuMoO4
(Institute for Low Temperature Physics and Engineering, 2018)
Thermochromic phase transition was studied in CuMoO4 using the Cu and Mo K-edge x-ray absorption spec-troscopy in the temperature range of 10-300 K. The hysteretic behavior has been evidenced from the tempera-ture dependence ...
Origin of Pressure-Induced Metallization in Cu3N: An X-ray Absorption Spectroscopy Study
(Wiley-VCH Verlag, 2018)
High-pressure (0–26.7 GPa) Cu K-edge X-ray absorption spectroscopy is used to study possible structural modifications of anti-perovskite-type copper nitride (Cu3N) crystal lattice. The analysis of X-ray absorption near-edge ...
Understanding of conversion process of magnetron deposited thin films of amorphous ReOx to crystalline ReO3 upon thermal annealing
(ACS Publications, 2020)
Thin films of rhenium trioxide (ReO3) were produced by reactive DC magnetron sputtering from metallic rhenium target followed by annealing in the air in the range of temperatures from 200C to 350C. Nanocrystalline ...
Synthesis and characterization of GaN/ReS2, ZnS/ReS2 and ZnO/ReS2 core/shell nanowire heterostructures
(Elsevier B.V., 2021)
Layered 2D van der Waals (vdW) materials such as graphene and transition metal dichalcogenides have recently gained a great deal of scientific attention due to their unique properties and prospective applications in various ...
