摘要

摘要介绍了通过分子束外延在硅基底上生长的掺砷 Cd0.3Hg0.7Te 固溶体层的光致发光（PL）研究结果。通过分析在不同温度和激发激光功率下获得的光致发光光谱，可以判断观察到的峰值的性质。确定了退火样品中砷的活化作用，其结果是形成了小的受体水平。砷作为镉汞碲化物的受体杂质的有效性已得到证实。

Photoluminescence of Arsenic Doped Epitaxial Films of Cd0.3Hg0.7Te

Abstract

The results of photoluminescence (PL) study of As-doped Cd_0.3Hg_0.7Te solid solutions layers grown by molecular beam epitaxy on a Si substrate are presented. Analysis of the PL spectra obtained at different temperatures and excitation laser powers allows one to judge the nature of the observed peaks. The activation of arsenic in annealed samples was established, as a result of which small acceptor levels are formed. The effectiveness of arsenic as an acceptor impurity for cadmium-mercury tellurides has been confirmed.
