Abstract
The present statement deals with the study of electrical conductivity measurements of CdSe-PVA undoped and CdSe-PVA doped with CU nanocomposite by chemical method. In the electrical measurements, the dark conductivity (σd) and the photoconductivity (σph) of CdSe and CDSE:Cu prepared thin films have been studied in the temperature cycle 308–343 K. The intensity on conductivity and effect of temperature has been analyzed for CdSe and CdSe:Cu nanocomposite films. The conductivity of every sample increases with increasing temperature representing the semiconducting activities of the sample. The value of dark activation energy is more than the photo activation energy due to the shift in energy levels under illumination.
