ABSTRACT
Zinc oxide (ZnO) has a wide band gap of 3.37 eV at room temperature. It is a piezoelectric material with high electrical mobility and high luminescence at room temperature. According to that, ZnO thin films have attracted attention in several modern devices like solar cells, gas detectors, optical and gas sensors, laser diodes, light emitting diodes and optoelectronic devices operating in the UV-visible (violet and blue) spectral range.
In this work, we are interested in developing ZnO thin films that elaborated by magnetron reactive sputtering. This technique process has high deposition rate, low-cost, good adhesion with the substrate, low deposition temperatures required, and a good parameters control. We try to optimize the conditions of elaboration and to study the influence of flow of oxygen on the different properties ZnO thin films. As well as their optimal flow rate, which gives it better physical properties necessary for applications in the field of optics and photovoltaics. We have deposited the ZnO films using a D.C reactive magnetron sputtering a different O2 flow rates. The correlation between optical and structural proprieties was investigated.
