Abstract :

Cadmium Zinc Sulfide (CdZnS) thin films have been deposited from their two binary compound CdS and ZnS by vacuum co–evaporation technique. The Structure, optical, and electrical properties of these films which deposited on heated glass substrate at 423 K under vacuum 10–5 mbar with thickness 500nm and deposition rate 0.833 nm/sec ,and treated at different annealing temperatures were carried out. X–ray diffraction analysis showed polycrystalline nature and have the hexagonal structure with strong preferential orientation along the (002) planes. The optical measurement showed the CdZnS films have direct energy gap (Eg),and its varies from 3.1 eV for as deposited to 3.4 eV for annealed film at 473 K. The electrical conductivity decrease many order when these films annealed at different annealing temperature.
