Electrical and Optical Properties of CdS Films prepared by Electrodeposition

Polycrystalline CdS films were grown on glass substrate with conducting indium tin oxide(ITO) by electrodeposition. The average size of the plate-shape grains o the CdS films was from 0.3um to 0.05um, and the adhesion to ITO was excellent. The optical band gap of the electrodeposited CdS films was in the range from 2.51eV to 2.68 eV. The optical transmittance was 80% and the electrical resistivity varied from 10$^3$ to 10$\^$5/$\Omega$-cm depending on the deposition condition.
