Study of electrical properties of CdSxSe1-x thin films by spray pyrolysis

ABSTRACT Electrical conductivity were studied by spray pyrolysis prepared CdSxS1-x thin films for all composition parameters x in the temperature range 77 K to 473 K. Conductivity of the films was of n-type. Donor activation energy systematically increase as composition parameter x increases. But conductivity decreases as temperature decreases for CdSe(x=0) films while conductivity increases as temperature decreases for CdS(x=1) thin films. Donor activation energy increases as the composition parameter x increases.
