Physics underpins most technological advance and as a result, has a key role to play in addressing the looming energy crisis. Whilst many of our research programs contribute to this effort, there are three principle areas in which clean energy research undertaken within the School.
Fusion Power: The basic principle of a fusion reactor is to heat a mass of hydrogen isotopes, deuterium and tritium, to many millions of degrees causing them to fuse together into helium releasing vast amounts of energy in the process. Fusion is attractive because it generates vast amounts of power without any greenhouse emissions or long-lived radioactive waste. The School hosts Australia's H-1 toroidal stellarator National Facility, which although on a smaller scale than prototype reactors such as ETA, offers excellent flexibility in its configuration. H1 is particularly suited to the development of advanced diagnostic instrumentation some of which has been employed on large-scale reactors overseas.
The School also has a research program focused on the development of plasma-based nanotechnologies to create highly efficient fuel cells. These cells use only 20% of the platinum of conventional cells and may represent a crucial step on the road to clean transport.
Multi-layer solar cells manufactured from compound semiconductors such as gallium arsenide have the potential to offer greatly increased efficiency over conventional silicon cells in certain applications. As part of our wider research program in the growth and fabrication of III-V semiconductor devices, the School has an active program in the application of these compounds to solar power generation.

Simplify nanowire solar cell fabrication by eliminating the need for p-n junctions to increase the ultimate device efficiency.
This project aims to develop III-V semiconductors for applicaiton in solar fuels generation.
In this project the wave-particle resonance condition will be computed for a range of precomputed particle orbits (and orbit populations), which initially were computed for transport studies. An estimate of wave-drive due to spatial gradients will be afforded using wave functions from an ideal MHD stability analysis and orbit population information, and compared to diagnostics.
This is an all-encompassing program to integrate highly sophisticated theoretical modelling, material growth and nanofabrication capabilities to develop high performance semiconductor nanowire array solar cells. It will lead to understanding of the underlying photovoltaic mechanisms in nanowires and design of novel solar cell architectures.
