摘要
In0.52Ga0.48-yAlyAs/InP multiple quantum well (MQW) structures are grown by gas source molecular beam epitaxy (GS-MBE). It is found that a transition from type I to type II structure occurs at an Al composiaon (y) of 0.18, accompanied by a drastic change of optical and electrical properties. The y dependence of the effective band gap of the InGaAlAs/InP MQW layers agrees well with the calculated result.
