Abstract	:	In this paper, the crystal structural and electrical transport properties of Lead Selenide thin films Were studied. For this purpose, high purity PbSe is thermally evaporated from molybdenum boat in vacuum of 10-6 Torr, onto glass substrates for structural and electrical transport measurements. X-ray diffraction patterns of powder PbSe showed polycrystalline structure of Cubic phase with lattice constants of: a = 6.1223 ?. X-ray diffraction patterns of PbSe thin films showed the crystal structure of Cubic system. It was found that annealing increases the degree of crystallininty.The transport electrical properties such as electrical resistivity ? was studied for deposited films of different thicknesses. It was found that for PbSe films the electrical conductivity is strongly affected by sample temperature, heat treatment and film thickness. PbSe films showed semi conducting behaviour. The dependence of electrical resistivity on film thickness showed that the electrical resistivity decreases as the film thickness increases. The activation energy ?E1, ?E2 of the free charge for PbSe samples was calculated using the electrical resistivity data at different temperatures for different thickness and was found to decrease as the film thicknesses increases.
