Summary on Grant Application Form |
|
The introduction of quantum wells has dramatically improved the performance of semi-conductor based Optelectronic devices allowing, for instance, high-speed optical communications, optical storage devices and high-power optical pump sources. Strain is important in all these applications, whether introduced deliberately to enhance device properties or whether present as an unavoidable consequence of growth and fabrication. We propose to establish general methods for calculating strain fields in semi conductor device structures and to use these as input for a systematic investigation of the unique electronic and optelectronic properties of strained quantum-wire structures. Our studies will focus on the optimisation of laser gain and threshold characteristics in strained quantum-wire lasers and the possibility of strain-induced subwire formation, establishing the extent to which the long-predicted benefits of quantum-wire lasers can be achieved in the medium term in state-of-the-art structures and also the possibility of novel routes towards wire formation. Our results will be communicated with and calculation carried out in close consultation with experimental groups in this area in the UK.
