Abstract
Todays, a lot of studies have been done in the fioeld of semiconductor materials and substitution effect of other elements on these materials. In this thesis, optical properties of sol-gel derived ZnO and Mn doped ZnO thin ilms with different thiknesses have been studied. The roughness of the prepared layers has been measured using confocal microscope.
The results of this investigation shows that the optical properties of pure and Mn doped ZnO is changed with the variation of surface roughness.
