SiO2 Encapsulant Enhanced Quantum Well Intermixing for InGaAsP Superlattice\+*
【摘要】 对晶格与 In P匹配的 In Ga As P超晶格结构外延片 ,运用等离子增强化学气相沉积法镀Si O2 膜 ,随后用碘钨灯快速热退火 ,进行无杂质空位扩散 ( IFVD)技术的实验研究 ,测量光致发光谱后得到了最大 50 nm的峰值位置蓝移 ;表明在没有掺杂和没有应变的情况下 ,IFVD仍有较好的处理量子阱材料的能力 .对影响 IFVD工艺的重复性因素进行了探讨 .
【Abstract】 Impurity Free Vacancy Diffusion (IFVD) technology on InGaAsP superlattice, which latticematches InP, is investigated experimentally, with SiO\-2 deposited by plasma enhanced chemical vapor deposition and rapid thermal annealing proceeded with iodine tungsten lamp. Up to 50nm blue shift of photoluminescence spectrum is observed, which shows IFVD has a capacity to treat QWs even without any impurities or strain. Factors are also discussed, that will affect the repetition of IFVD.
