Stability Effect In Photoconducting Studies Of Some Chemically Deposited Cds, (Cd-Pb)S And (Cd-Zn)S Films, Shashi Bhushan, Tandesh Chandra
Turkish Journal of Physics
Stability effects in photoconductivity (PC) rise and decay have been studied over a period of 2 years in thin films of (Cd-Pb)S:LiF, La/Pr and (Cd-Zn)S: LiF,La/Pr and have been found quite stable; however, those of CdS are not that stable. Results of annealing effect are also included, which present more stable values. XRD studies show prominent lines of base materials. Further, XRD and SEM studies show the particle sizes are in the nanometer range. Results of optical absorption spectra have been used to evaluate the band gap of the materials. Effect of thickness of the Ag electrode has also been …
