Synthesis and characteristics of screen printed ZnO thick films nanostructures grown using different methods

Abstract

Zinc oxide nanostructures prepared using two different methods: first method (simple evaporation) with different flow rates of (100, 200 and 300) (sccm) using a mixture of (Ar + O2)with a ratio of (10:1). The second method (hydrothermal) zinc nitrate aqua solution and Teflon lined stainless steel autoclave was used as a reactor. The ZnO powders were deposited on different substrate using screen print technique also the conducting electrodes deposited by the same technique which is simple low cost and eligible for mass production. Field emission scanning electron microscope, Atomic force microscope was used to study surface morphology of the films and X-Ray diffraction to study the structural properties of the films. Also the electrical properties of the n-ZnO/p- Si devices were investigated.
