Abstract ZnTe thin films were grown on glass substrates using vacuum evaporation technique. A cylindrical furnace is designed for substrate heating, which improve the crystallite size and stoichiometry over wide substrate temperature range. The variation of electrical resistivity and photosensitivity are explained on the basis of stoichiometric composition and improvement in the crystallite size of ZnTe films deposited at different substrate temperatures. The effect of films thickness variation on the electrical resistivity have been studied. Efforts of impurities doping in ZnTe films for improving the conductivity of ZnTe film are not successful on account of self‐compensation effect.
