The Effect of Temperature Annealing on the Electrical and Electro - Optical Properties of Cadmium Oxide Thin Films Prepared by SILAR Method


Cadmium oxide thin films have been prepared on glass substrate at 363K temperature by SILAR (successive ionic layer adsorption and reaction)technique using cadmium acetate solution . The CdO thin films were annealed at 673 and 773 K under atmosphere for 45 min. The electrical and electro – optical properties were studied. Electrical studies showed that the thermal-electrical conductivity and activation energies influenced by thin films annealing . The photoconductivity of CdO thin film for annealed and non- annealed films are studied. It was found that electrical conductivity increased with annealing temperatur
