Summary on Grant Application Form
Low-dimensional semiconductor quantum structures, e.g. the 2D electron system in GaAs-AlGaAs heterostructures, not only form the basis for much fundamental physics research but also have considerable technological significance as transistors, microwave diodes, resonant tunnelling devices, lasers, modulators, infra-red detectors and solar cells. We have long since recognised that there is a close relationship between new technology and new science and therefore we continue to develop advanced technology to produce new types of semiconductor structures. We have introduced new lithographic techniques for the fabrication of nanoscale electronic devices. Our ex-situ electron beam lithography, produced the first one-dimensional electron system, the first controllable quantum interference devices and the first zero-dimensional quantum dot. These developments led to the creation of a new field in experimental mesoscopic physics resulting in world-wide activity. Subsequently we developed in-situ focused ion beam techniques which can pattern the semiconductor structure during and between growth sequences. New physics in the form of electronic drag, solid state spectroscopy, tunnelling, non-invasive detection and the manipulation of single electrons has emerged. This new proposal identifies a range of technological developments and structures which will provide a deeper understanding of much fundamental physics as well as benefiting applied physics research.
