Features of semiconducting properties of ceramic samples ZnSe with admixtures lithium and copper

Abstract

We have researched intentionally unalloyed and alloyed by lithium and copper ceramic samples ZnSe with various contents of admixtures. It is discovered that with the increase of admixture contents the electric conductivity of samples is increasing non-proportionally to the increase of concentration. Dependence of the value of conductivity of admixture concentration has the area of the sharp increase of electrical condcutivity of samples on the condition of concentration increase for one order of the value. The discovered particularity of conductivity is explained on the base of the theory of proceeding streaming the lumpy systems. The spectrum of photoluminescence of ZnSe ceramics depends on the nature and concentrations of alloyed admixtures.
