介绍了在Si衬底和石英玻璃衬底上生长的立方相MgxZn1-xO(0.55≤x≤1)晶体薄膜的物理特性,AFM和XRD等微结构特性表征显示了良好的表面形貌和高度的(111)取向生长特性.采用Manifacier方法,根据透射光谱中的干涉峰,计算得到立方相MgxZn1-xO薄膜的折射率.与已报道的六方相MgxZn1-xO(0≤x≤0.5)薄膜的折射率相类似,在400~800nm的可见光区域,不同Mg含量的立方相MgxZn1-xO薄膜,其折射率随入射波长的色散关系遵循一阶Sellmeier方程.对给定400nm的入射光波长,当薄膜中的Mg含量由55%增至100%时,其折射率由1.89衰减至1.73.
