Inorganic Materials Aims and scope

Abstract

The transmittance of Zn1−x Cd x As2 anisotropic single crystals in their transparency region is found to depend on the incident light polarization, photon energy, and sample thickness. This effect is shown to be associated with light scattering in Zn1−x Cd x As2, which can be understood in terms of the crystal structure of the monoclinic crystals. The fundamental absorption edge in Zn1−x Cd x As2 is dominated by an indirect forbidden transition for the E ‖ c polarization and by a direct forbidden transition for E ⊥ c.
