Study of Sol-Gel Chemical Process for the Creation of ZnO Thin Films

ZnO-focused research goes back so several decades, when doped with transition metals, the renewed interest is fuelled by the availability of high quality substrates and reports of ferromagnetic and p-type conduction behaviour. . For the ZnO nanomaterials synthesis, various techniques such as spray pyrolysis, sol-gel, wet chemical processes, thermal evaporation, etc are used. The interest growing in this material arose from the advancement of growing technologies for the manufacture of high-quality epitaxial layers and single crystal, which enable the realization of optoelectronic and nanoelectronic devices based on ZnO. This paper focus on study of Sol-Gel chemical process for the creation of ZNO thin films.
