Silver diffusion in cadmium sulfide single crystals

An experimental study was made of the penetration of silver by the thermal-diffusion method into cadmium sulfide. The silver was deposited on the samples by thermal evaporation in vacuum. Optical and electrical-probing methods were used to study the rates of surface and bulk diffusion at various temperatures. The temperature dependence of the diffusion coefficient was established for the purity used. After the penetration of the silver impurity, the low-resistivity ( 0.1 · cm), nonphotosensitive cadmium sulfide samples displayed high resistivity ( 10⁶-10⁸ · cm) and photosensitivity.Translated from Izvestiya VUZ.
