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.

Auger electrons are emitted after nuclear decay and are used for medical purposes. The number of Auger electrons generated per nuclear decay is not known accurately, a fact that hinders medical applications. This project aims to obtain a experimental...
Scanning electron microscopy is a powerful tool for materials and this method is believed to correctly identify depletion regions in semiconductor devices. This project links the electron microscopy contrast to the depletion regions measured by capacitance-voltage...
This project investigates the structure and density of defects created in 2D materials by energetic ion irradiation, and studies how such defects affect the physical properties of this important class of materials.
Uniform composition and tunability over the emission wavelength of ternary nanowires is an important challenge for nanowire growth. Growth of nanowires combined with a range of characterisation techniques including electron microscopy will be used for this...
