Abstract Fabry-Perot (F–P) microcavities were constructed in stable rock-salt (RS) structural Mg0·21Zn0·79O/MgO multiple-quantum-well (MQW) with perfect hetero-interface and wide band gap energy (4.930 eV). Obvious F–P interference patterns were observed in both of the transmission and photoluminescence spectra. The transfer matrix method was employed to analyze the F–P interference patterns. In-plane compressive stress-induced double sets of PL interference patterns were observed in the RS-Mg0.21Zn0·79O/MgO MQW. Such a strained MQW with inherent microcavity could be useful for high performance light-emitting devices.

来自岩盐 MgZnO/MgO 多量子阱的 Fabry-Pérot 干涉效应

摘要 在稳定的岩盐 (RS) 结构 Mg0·21Zn0·79O/MgO 多量子阱 (MQW) 中构建了法布里-珀罗 (F-P) 微腔，具有完美的异质界面和宽带隙能量 (4.930 eV) . 在透射和光致发光光谱中均观察到明显的 F-P 干涉图案。采用转移矩阵法来分析 F-P 干涉图样。在RS-Mg0.21Zn0·79O/MgO MQW中观察到面内压应力引起的双组PL干涉图样。这种具有固有微腔的应变 MQW 可用于高性能发光器件。
