In the present investigation thin semiconductor films of CdS, Bi 2 S 3 and their intermixed composite films have been electro-synthesized onto conducting glass substrate from nonaqueous bath containing various levels of the precursor salts of Cd 2+ and Bi 3+ . Spectrophotometric measurements determine the band gap energies of the composite films at ∼2.53eV and ∼1.37eV...
In the present investigation, polycrystalline n-CdTe films have been synthesized on SnO 2 -coated glass substrate employing voltammetric technique under periodic cycles. Optical properties of the CdTe films were investigated and the band gap energy was found to lie within the range of 1.32–1.40eV depending on the composition of the film matrix, as obtained by EDAX analysis. The films were...
