Local electronic structure rearrangements and strong anharmonicity in YH3 under pressures up to 180 GPa
(Nature Research, 2021-03)
The discovery of superconductivity above 250 K at high pressure in LaH10 and the prediction of overcoming the room temperature threshold for superconductivity in YH10 urge for a better understanding of hydrogen interaction ...
The local atomic structure and thermoelectric properties of Irdoped ZnO: hybrid DFT calculations and XAS experiments
(Royal Society of Chemistry, 2021)
We combined the hybrid density functional theory (DFT) calculations and X-ray absorption spectroscopy (XAS) experiments in the study of the local atomic structure around Ir ions in ZnO thin films with different iridium ...
Ab-Initio Calculations of Oxygen Vacancy in Ga2O3 Crystals
(Sciendo, 2021)
Gallium oxide β-Ga2O3 is an important wide-band gap semiconductor. In this study, we have calculated the formation energy and transition levels of oxygen vacancies in β-Ga2O3 crystal using the B3LYP hybrid exchange-correlation ...
Comparative Hybrid Hartree-Fock-DFT Calculations of WO2-Terminated Cubic WO3 as Well as SrTiO3, BaTiO3, PbTiO3 and CaTiO3 (001) Surfaces
(MDPI, 2021)
We performed, to the best of our knowledge, the world’s first first-principles calculations for the WO2-terminated cubic WO3 (001) surface and analyzed the systematic trends in the WO3, SrTiO3, BaTiO3, PbTiO3 and CaTiO3 ...
Vacancy defects in Ga2O3: First-principles calculations of electronic structure
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
First-principles density functional theory (DFT) is employed to study the electronic structure of oxygen and gallium vacancies in monoclinic bulk β-Ga2 O3 crystals. Hybrid exchange– correlation functional B3LYP within the ...
Tendencies in abo3 perovskite and srf2, baf2 and caf2 bulk and surface f‐center ab initio computations at high symmetry cubic structure
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
We computed the atomic shift sizes of the closest adjacent atoms adjoining the (001) surface F‐center at ABO3 perovskites. They are significantly larger than the atomic shift sizes of the closest adjacent atoms adjoining ...
