Study of Some Optical, Electrical Properties of ZnO Thin Films Deposited by Chemical Spray Pyrolysis Method
AbstractIn 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.
