摘要

利用金属有机源化学气相沉积(MOCVD)生长方法

在2.5 kPa和5 kPa生长压强下

分别以sapphire(Al

)和ZnO为衬底生长ZnMgO薄膜。研究分析了样品的晶体结构、表面形貌、光电学性质。结果表明

衬底和生长压强对ZnMgO薄膜的生长有重要影响。5 kPa高压生长和以ZnO为衬底均有利于ZnMgO薄膜中Mg的掺入。

Abstract

ZnMgO films were grown on the Al

(sapphire) and ZnO substrates by metal-organic chemical vapor deposition (MOCVD) under different pressures. By analyzing the crystal structure

surface properties

optical and electrical properties of ZnMgO films

We found that different substrates and pressures have an important influence on growth and properties of ZnMgO films.Both high pressure of 5 kPa and ZnO substrate are better for Mg doping in ZnMgO.
