Influence of MOVPE growth conditions and substrate parameters on the structural quality of multi-period InGaAsP/InP MQW structures

Abstract

In this work we have investigated the MOVPE growth of multi-period InGaAsP/InP quantum confined Stark effect (QCSE) layer structures and provide evidence that the QCSE response can be influenced by optimizing the gas exchange procedure, mainly to minimize carry-over effects. Secondly, we present new results on the thermal stability behaviour of these MQW structures which appear to be strongly related with the underlying buffer layer and substrate material.
