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.

Highlights

Metal-oxide semiconductors (MOS) had a great amount of attention for their applications in several areas such as medical diagnosis, toxin gases sensors and opto-electronic industries [1, 2]

Summary

Introduction

Metal-oxide semiconductors (MOS) had a great amount of attention for their applications in several areas such as medical diagnosis, toxin gases sensors and opto-electronic industries [1, 2]. Since the control of the size and shape of nanostructure materials plays main role and great effect on the physical properties of the materials, several methods and techniques are used to synthesize different materials including ZnO Nanostructures, such as Pulse laser deposition (PLD), Chemical vapor deposition (CVD), Chemical bath deposition (CBD), Hydrothermal and chemical reactions. Among these methods, the simple evaporation method is preferred due to its low cost and high quality products [10]
