摘要

摘要本文介绍了对 Hg0.7Cd0.3Te 块状晶体和通过不同方法生长的外延薄膜的光学和结构特性进行比较研究的结果。在 4.2-300 K 温度范围内进行的光致发光研究数据显示，不同样品的光学特性相似，并表明固溶体存在明显的无序性。不过，根据 X 射线衍射数据，无序的程度与材料的结构质量没有直接关系。本文讨论了在光电子学应用中使用通过各种方法生长的材料的前景。

Optical and Structural Properties of Hg0.7Cd0.3Te Epitaxial Films

Abstract

The results of comparative studies of the optical and structural properties of Hg_0.7Cd_0.3Te bulk crystals and epitaxial films grown by various methods are presented. The data of photoluminescence studies performed in the temperature range 4.2–300 K showed the similarity of the optical properties of different samples and indicated a significant disordering of the solid solution. According to X-ray diffraction data, however, the scale of the disordering was not directly related to the structural quality of the material. The prospects for using the material grown by various methods in optoelectronics applications are discussed.
