Description 624-627
Cadmium sulphide thin films deposited on glass substrates are found to be polycrystalline having hexagonal type structure. The photocurrent-light intensity characteristics show sub-linear and super-linear behaviour which are attributed to the defects. The defect characterization is done from the temperature dependence of dc photoconductivity and rise and decay characteristics of the photocurrent. shallow levels (0.06 to 0.34eV) arising from interstitial cadmium or sulphur vacancies are found to cause extrinsic photoconductivity near room temperature whereas the deep levels dominate the rise and decay characteristics and superlinearity.
