Abstract : In the present work, the structural properties of thermally evaporated CdSe films prepared at different thicknesses has been undertaken and the conduction mechanism is studied for the film of thickness 100nm. It is noted from the result that, all the films prepared at room temperature are poly crystalline and the peak oriented towards (002) plane and the peak corresponding to (103) plane begins to emerge when the thickness increases. From the analysis of the ac conductance mechanism, it is noted that it varies according to the relation Gp α ωn and‘n’ is found to vary depending on the frequency and temperature range studied, which suggests that the conduction mechanism in CdSe thin films are by means of hopping.
