ZnxCd(1-x)Te thin films of variable composition have been investigated. Structural and optical properties of ZnxCd(1-x)Te solid solution with x = 0.1, 0.2, 0.3, 0.4, and 0.5 were synthesized, from the resulting ZnTe and CdTe composition used in preparation of thin films. Structural investigation indicates they have polycrystalline structure. Composition was confirmed from EDAX while SEM picture shows homogeneity in films. Plots of (αhν)2 versus (hν) yield straight line indicating direct transition. It is also found with increase Zn content the band gap of the films increases.Keywords
