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

You could be doing your own research into nanoscience and nanotechnology. Below are some examples of student physics research projects available in our school.

Shape engineering of semiconductor nanostructures for novel device applications

This project aims to investigate the growth of III-V semiconductors on pre-patterned nanotemplates. By using different shapes and geometries, it is envisaged that these nanostructures will provide novel architectures for advanced, next generation optoelectronic devices.

Functional nanopore membranes

Nano-pore membranes have important applications in chemical- and bio-sensing, water filtration and protein separation. This project will investigate our innovative technology to fabricate nanopore membranes in silicon dioxide and silicon nitride and exploit their use for advanced applications.

Surface forces and the behaviour of colloidal systems

We measure the basic forces that operate between molecules that are manifest at interfaces. These forces control the stability of colloidal systems from blood to toothpaste. We use very sensitive techniques that are able to measure tiny forces with sub nanometer distance resolution. Understanding these forces enables us to predict how a huge variety of colloidal systems will behave.

Quantum-well nanowire light emitting devices

In this project we aim to design and demonstrate  III-V compound semiconductor based quantum well nanowire light emitting devices with wavelength ranging from 1.3 to 1.6 μm for optical communication applications.
