Electrical properties of nano crystalline ZnxCd1-xS thin films prepared by CBD technique

Abstract EN

Nanocrystalline zinc cadmium sulfide (ZnxCd1-xS) thin films were deposited on glass substrate by chemical bath deposition (CBD) technique using the mixed aqueous solution of zinc chloride ((ZnCl2), cadmium chloride (CdCl2), thiourea (CS(NH2)2) and ammonia solution (NH4OH).

The as deposited films were characterized by high quality instrument type (HMS-3000).

The results show that all the prepared films have n-type conductivity; this is concluded from the Hall measurements.

The electrical conductivity is found to decrease with increasing x, while the activation energies are found to be increasing from (0.458 to 0.860 eV) as x increase from ( 0.1 to 0.9).
