Abstract:
Investigations have been carried out on the determination of the optical band gap by photoconduction measurements in cadmium phosphates. Gas thin films, and A12O3 in the form of thin film as well as single crystal. In addition to obtaining the band gap for these materials, we have also studied the traps in these materials. Interfacial surface states in MOS system have also been investigated.
Many traps also exist in these materials and their photo depopulation yields the observed photoconduction.
