CdSe is an important compound semiconducting material for the development of various applications in solid state devices such as solar cells, high efficiency thin film transistors. In recent years major attention has been given to the investigation of structural properties for the improvement of performance of such devices and applications. The prepared starting materials have composition Cd1 – xSex (0.22 ≤ x ≤ 0.40) was used to fabrication of thin films. The n-type cadmium selenide thin films have been deposited by electron beam evaporation technique on well cleaned glass substrate in vacuum ~10 – 5 torr keeping substrate temperature at 300 K. The resistivity, conductivity, Hall mobility and carrier concentration of the deposited films were calculated of different compositions ratio of Cd/Se.
