Recombination properties of ZnIn/sub 2/S/sub 4/:Mn single crystals

Abstract

Recombination characteristics of single crystals of Mn-doped ZnIn/sub 2/S/sub 4/(III) three-layer polytypes have been investigated. The characteristic Features of cathodoluminescence (CL) have been found out. The CL spectra shift toward the long wavelength range is observed when the dopant concentration increases and temperature decreases till 80 K. The photoconductivity (PC) spectra shift to the high energy region and the PC type changes with the increasing of the dopant concentration. Doping with Mn increases the order of the crystal. A model for the interpretation of the experimental data is proposed.
