Abstract

The structural, vibrational, and electrical properties of ZnSe crystals grown by chemical vapor deposition (CVD) were investigated. X-ray diffraction analysis confirmed the formation of high-quality cubic sphalerite ZnSe with pronounced (111) crystal texture, submicron crystallite size, and high structural homogeneity. Elemental composition analysis revealed near-stoichiometric ZnSe with minor selenium excess, while Raman spectroscopy identified well-defined transverse (TO) and longitudinal (LO) optical phonon modes, indicating low structural disorder. Impedance spectroscopy showed that the electrical conductivity of ZnSe polycrystals exhibits frequency-dependent dispersive behavior, consistent with hopping conduction of localized carriers. The results demonstrate that CVD-grown ZnSe crystals possess high structural and chemical quality and are promising materials for optoelectronic applications.
