摘要
首先从理论上研究了在应变情况下量子阱中能级的计算,然后利用LP-MOCVD研究了InGaAs/InP组份的控制及生长条件,最后生长伸张应变为0.5%的四个量子阱InGaAs/InP结构材料,利用PL光谱测量得最小阶宽为1.8nm。
The energy levels of quantum well (QW) under differential strain have been calculated,the composition and growth rate of InGaAs matched with InP have been studied by Low Pressure Metallorganic Chemical Vapour Deposition (LP-MOCVD). Four-QW InGaAs/InP with 0. 5% tensile strain has been grown.The narrowest well width is 1. 8 nm by PL spectroscopy measurement.
