研究了高压布里奇曼法生长的锌镁硒混晶的光电性能。测量了光电导的光谱分布和温度特性，以及发光和光导的热刺激和猝灭。用统计涨落引起的随机局部电势起伏(RLPF)讨论了存储载流子的弛豫。根据在−_xSe中观察到的光致发光现象，讨论了II-VI固溶体在构建光电子器件方面的潜在应用。(2014Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
Photoelectric properties of Zn0.8Mg0.2Se mixed crystals grown by high pressure Bridgman method were investigated. Spectral distributions and temperature characteristics of photoconductivity as well as thermal and optical stimulation and quenching of luminescence and photoconductivity were measured. Relaxation of stored carriers were discussed in terms of random local potential fluctuation (RLPF) due to statistical fluctuations of composition. Based on the observed photoinduced phenomena in ZnxMg1−xSe, the potential applications of II–VI solid solutions for construction of optoelectronic devices were discussed.
