Abstract

Using the capabilities of the CRYSTAL14 code, the parameters of an equilibrium crystal lattice are obtained and the electronic and vibrational structures of a new chalcopyrite-like Zn2SeTe crystal are studied. The energy band structure, long-wave vibrational frequencies at the point Г, and elastic moduli are calculated. The dependence of the contributions from the vibrations of individual atoms to the vibrational modes of a crystal caused by filling the cationic or anionic sublattices in the chalcopyrite structure is established.
