Abstract
In this article, the problem of stability of AIIBIVAs2 (A = Cd, Zn, B = Ge, Si) compounds as the continuous solid solution composition AIIBIVAs2 with the structure of chalcopyrite in the state of quantum dots of nanoelectromechanical systems (NEMS) is studied. Variations of energy, geometry, and paired radial distribution functions of atoms of stable NEMS quantum dots of AIIBIVAs2 at a temperature of 0 K are investigated. It is revealed that the relative change in the parameters of stable AIIBIVAs2 nanolayers in the state of NEMS quantum dots depends nonlinearly on the concentration of zinc or germanium atoms in the system. It was shown that this behavior is a result of the significant difference in energy and lengths of NEMS Ge-As and Si-As bonds belonging to the first coordination sphere of arsenic atoms.
