摘要
金属有机物化学气相沉积(MOCVD)方法生长应变InGaAs/GaAs量子阱,应变缓冲层结合生长中断改善量子阱的PL谱特性.用该量子阱制备的激光器有很低的阈值电流密度(43 A/cm^2)和较高的斜率效率(0.34W/A,per facet)。
Strain buffer layer and growth interruption were applied in the QW growth by mentalorganic chemical vapor deposition (MOCVD) to improve QW photoluminescence performance. The laser diodes using the QW have very low threshold current densities (43 A/cm2) and high slop efficience (0.34 W/A, per facet).
