Description

Full text: Self-assembled InAs/lnP quantum dots (QDs) are very promising active materials for QD lasers and semiconductor amplifiers for optical fiber communications (1.3-1.55 mm). However the main challenge associated with this material system is the As/P exchange reaction which degrades the structural and optical properties of the QDs. In this talk, we will show the effect of growing a thin spacer layer of GaAs or InGaAs prior to the deposition of the InAs QDs by metalorganic chemical vapor deposition. Not only the effect of As/P exchange is suppressed or minimized but the bandgap of the QDs could be tuned too. Copyright (2005) Australian Institute of Physics
