ZnO nanostructures growth at low temperature from Zn powder and Zn Acetate

POSTER

Abstract

In this work we report the synthesis of various types of ZnO nanostructures under two different approaches: Vapor Phase Transport process (VPT) using Zinc acetate as the source material, and simple thermal evaporation of Zinc powder (99.9{\%}). Each process has specific growth parameters. ZnO nanostructures were synthesized on silicon and sapphire wafers at temperatures ranging from 360\r{ }C to 500\r{ }C. Comparison of Atomic Force Microscope (AFM) images and of Scanning Electron Microscope (SEM) images show that the precise control of the gas flow (O$_{2}$/Ar mixture), as well as the growth time, are key in the formation, size and shape of the nanostructures. Low Temperature Photoluminescence measurements indicate that the depositions are of very good quality.
