A new trigonal (rhombohedral) SiC phase, existence of which was previously theoretically predicted by a symmetry analysis, is studied. It is shown that the phase can be formed during the growth of SiC films by the method of substitution of atoms on t

Magnetotransmission (MT) at magnetic fields up to 29 T was used to study the electronic structure of $\mathrm{CuInS}{\mathrm{e}}_{2}$ in thin polycrystalline films. The zero field absorption spectra exhibited resolved A, B, and C free excitons. Quant

Three different transition paths of the phase transition from the high-symmetry trigonal P3¯ m1 to the low-symmetry monoclinic phase C2/c in K3Na(SeO4)2 crystals have been analyzed using ab initio calculations based on the density functional theory

The atomic sublattices occupying different Wyckoff positions in a host crystal are shown to be subdivided in the supercell model owing to the splitting of the occupied Wyckoff positions. The site symmetries of the split Wyckoff positions are in gener
