InAs Quantum Dots for Optoelectronic Device Applications

In this paper we discuss the growth of self-assembled InAs quantum dots (QDs) on both GaAs and InP substrates by low pressure Metal Organic Chemical Vapor Deposition. The influence of various growth parameters, such as the deposition time, the QD overlayer growth temperature, the V/III ratio and the group III and/or group V interdiffusion on QD formation are discussed and compared for the two systems. Stacking issues and preliminary results for an InAs/GaAs QD laser are also presented.
