Study of some structural , optical, Electrical Properties of ZnO thin films deposited by chemical Spray Pyrolysis Method

Abstract

In this research we prepared ZnO thin films by Spray pyrolysis method with thickness (300nm) on a glass substrates and study its optical and electric properties.The results of (X-Ray ) diffraction showed that the films have a polycrystalline structure، The Absorption and The transmission as a function of photon energy for ZnO films had been studied، The investigated of energy gap of the direct allowed transitions of ZnO film showed a value of (3.14 eV). The optical Absorption coefficients have been study as a function of Photon Energy. Seebeck measurements revealed that ZnO thin films are n-type.
