Nanoscience and nanotechnology

We conducts extensive research into the design, growth and fabrication of semiconductor and optical devices on the nanometer scale using techniques ranging from MOCVD growth to ion beam processing. Such devices by virtue of their scale, exploit quantum effects to enhance their performance. A large part of this research program focuses on quantum well lasers and detectors of importance to the telecommunications industry.

We also research the nanoscale modification of bulk materials such as nanocrystals within semiconductors induced by ion irradiation. materials modified in this way can have unusual and technologically useful properties such as light emission at wavelengths incompatible with the bulk material band structure.

Nanotubes as their name suggests are microscopically small pipes of material such as carbon - like an elongated form of a "buckie ball". These have exciting properties such as unimaginably high tensile strengths and the School has an active research program on the efficient production of nanotubes by mechano chemistry.

Potential student research projects

Nanowire lasers for applications in nanophotonics

This project aims to investigate the concepts and strategies required to produce electrically injected semiconductor nanowire lasers by understanding light interaction in nanowires, designing appropriate structures to inject current, engineer the optical profile and developing nano-fabrication technologies. Electrically operated nanowire lasers would enable practical applications in nanophotonics.
