Abstract

The influence of annealing in zinc vapor on the impurity-defect composition and the IR cathodoluminescence (CL) of ZnSe:Te plates diffusion-doped with iron is studied. Formation of precipitates on twin boundaries is found. It is shown that annealing of structures with surface iron concentrations exceeding 1 at % in zinc vapor leads to a significant increase in the IR CL intensity. It is found that interband luminescence in the regions with high iron concentrations is partially restored as a result of annealing.

锌蒸气退火对ZnSe：Fe 2+可见光和中红外发光的影响

摘要

研究了锌蒸气中退火对扩散掺杂铁的ZnSe：Te板的杂质缺陷组成和红外阴极发光（CL）的影响。发现在双边界上形成沉淀。结果表明，对锌蒸气中表面铁浓度超过1 at％的结构进行退火会导致IR CL强度显着提高。发现通过退火，铁含量高的区域中的带间发光被部分恢复。
