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 ...
Distinctive features of diffusion-controlled radiation defect recombination in stoichiometric magnesium aluminate spinel single crystals and transparent polycrystalline ceramics
(2020)
MgAl2O4 spinel is important optical material for harsh radiation environment and other important applications. The kinetics of thermal annealing of the basic electron (F, F+) and hole (V) centers in stoichiometric MgAl2O4 ...
On the Way to Optoionics
(Wiley Blackwell, 2020)
Based on the recent finding of significant ion conduction enhancement in iodide perovskites upon illumination, the potential of an emerging field ‘opto-ionics’ – that we define in parallelism to ‘opto-electronics’ – is ...

Study of High-Temperature Behaviour of ZnO by Ab Initio Molecular Dynamics Simulations and X-ray Absorption Spectroscopy
(MDPI, 2021)
D.B., M.K. and A.K. acknowledge access to Piz Daint at the Swiss National Supercomputing Centre, Switzerland (CSCS) under the project ID sm02. The experiment at the MAX IV synchrotron was performed within the project ...
Evidence for the formation of two types of oxygen interstitials in neutron-irradiated α-Al2O3 single crystals
(Nature Research, 2021)
Due to unique optical/mechanical properties and significant resistance to harsh radiation environments, corundum (α-Al2O3) is considered as a promising candidate material for windows and diagnostics in forthcoming fusion ...
Exciton interaction with Ce3+ and Ce4+ ions in (LuGd)3(Ga,Al)5O12 ceramics
(Elsevier B.V., 2021)
Scintillators based on Ce-doped garnets are regularly co-doped with Mg2+ or Ca2+ to form Ce ions in 4+ state and reduce undesired afterglow. However overly high Ce4+ concentration leads to poor light yield performance. In ...
Vibrational analysis of paraelectric–ferroelectric transition of linbo3: An ab-initio quantum mechanical treatment
(MDPI, 2021)
The phase transitions between paraelectric (PE) and ferroelectric (FE) isomorph phases of LiNbO3 have been investigated quantum mechanically by using a Gaussian-type basis set, the B3LYP hybrid functional and the CRYSTAL17 ...
