Abstract :
In this papers we worked to find the comparing of deposit time of thin films and find that the films deposited at 60
minutes and 90 minutes it’s the best films as compared with 30 minutes and 120 minutes in a structure and the optical properties exception of optical properties transmittance and absorbance. Films transmittance values decreased with increasing of the deposition time, but that’s lead to increase in absorbance values. Energy gap depends on thickness and grain size. Films that deposit at 120 min has more thickness than the one at 90 min., 60 min. and 30 min. films. All that after annealing temperature at 400 Cº and 500 Cº . Grain size of films that treated at 500 Cº is greater than the films that treated at 400 Cº. Grain size appears, affected by the increasing of annealing temperature and deposition time.
