摘要

利用脉冲激光沉积技术在非晶石英衬底上制备立方结构MgZnO薄膜，并研究MgZnO薄膜结晶特性、光学带隙随生长温度的变化情况。当生长温度从150℃升高到700℃时，MgZnO薄膜的生长取向由（200）向（111）转变。在600℃以下，MgZnO薄膜光学带隙的变化规律与晶格中Mg和Zn原子比例的变化趋势是一致的;而当温度升至700℃时，虽然MgZnO晶格中Mg和Zn原子比例降低，但由于平均晶粒尺寸变大，薄膜的光学带隙反而上升。在300℃和700℃晶格匹配的情况下，获得了单一（200）和（111）取向的立方MgZnO薄膜。

Abstract

Cubic structure Mg

O films were deposited by pulsed laser deposition method. The influence of temperature on the growth orientation and optical absorption characteristics of cubic structure Mg

O films were studied. The preferred growth orientation of MgZnO thin films changed from (200) to (111) when the growth temperature increased from 150℃ to 700℃. The UV absorption edge of MgZnO thin film changed with the Mg/Zn ratio in MgZnO crystal lattice when the growth temperature increased from 150℃ to 600℃. When the temperature changed from 600℃ to 700℃

the grain size of MgZnO thin film increased

and the UV absorption edge of MgZnO thin film blue shifted though the Mg/Zn ratio in MgZnO crystal lattice decreased. Finally

single (200) and (111) orientation MgZnO thin films were deposited on (200) and (111) orientation MgO substrates at 300℃and 700℃

respectively.
