Thenanocrystalline Sb & Se co-doped PbTe thin films were prepared by using an integrated physical-chemical approach by evaporating chemically synthesized Sb& Se co-doped PbTenanopowders on glass substrates. The prepared films were analysed by XRD, SEM, EDAX and their results were discussed in detail. The DC electrical conduction mechanism in Al/SbPbTeSe/Al thin film sandwich system at different temperatures (298–423 K) was studied and was found to be Poole-Frenkel type.
