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.
See beck measurements revealed that ZnO thin films are n-type.
