(d.c) electrical conductivity of ( CdSe0.5Te0.5) thin films which formed at different rates of deposition

Abstract

The aim of this research is to prepare ( CdSe0.5Te0.5) thin films by vacuum thermal evaporation method ,and study the direct electrical conductivity and calculating activation energy values of thin films which prepared at different rates of deposition (0.25,0.50,0.75) nm/s . The study of relation ship between electrical conductivity and temperature has shown that the electrical conductivity increase with temperature increasing ,and the study of relation ship between electrical conductivity with rate of deposition has shown that the electrical conductivity increase with rate of deposition increasing ,while the activation energy values decrease
