ABSTRACT

X-ray structural analyzes of CVD ZnSe polycrystalline samples were conducted, surface morphology and microstructure were studied, frequency and temperature dependences of real and imaginary parts of electrical conductivity and dielectric permeability were studied by impedance spectroscopy method. It is determined that the sample consists of one phase, the existence of a dominant direction, and that it crystallizes in a surface-centered cubic syngonia, and the elementary lattice parameter is determined. It was found that the activation energy changes depending on the frequency and temperature, the electrical conductivity is realized by zone-by-zone and jump mechanisms, and the polarization dispersion is relaxational.

Keywords: electrical conductivity, hopping mechanism, dielectric permittivity, relaxation dispersion, dipole polarization.
