    • Abstract

       

      Thin films of CdSe1−xTex were prepared by using electro deposition with varying doping concentrations of Te(x). Photoconductive studies as a function of applied field, time, wavelength, and intensity of incident light were carried out at room temperature between 1 and 3·5 eV. After establishing that the electrode contacts made using silver paint were ohmic, it was found that as the concentration of Te(x) increases in CdSe1−xTex, the band gap of the material decreases according to the empirical relationEg = (2 − 1·5x)eV.
