Collision data for lighting industry and plasma modeling. The project's primary aim is to progress the design of more efficient
and environmentally friendly light sources. Given the number of light
sources in use worldwide even a small improvement in the efficiency
could lead to enormous benefits to society via reduction of energy
consumption. Design of new mercury-free light sources will eliminate a
major neuro-toxin pollution source. Collaboration with research groups

Power scaling of remote plasma sources for gallium nitride film growth with real-time monitoring of activated nitrogen species. Domestic, industrial and community lighting currently accounts for ~20% of the world's overall energy consumption. Commonly used incandescent lights are based on inefficient, century-old technologies. In contrast, light emitting diodes (LEDs) use ~80% less energy and last ~100 times longer. LED deployment will bring substantial economic and environmental benefits for Au ....Power scaling of remote plasma sources for gallium nitride film growth with real-time monitoring of activated nitrogen species. Domestic, industrial and community lighting currently accounts for ~20% of the world's overall energy consumption. Commonly used incandescent lights are based on inefficient, century-old technologies. In contrast, light emitting diodes (LEDs) use ~80% less energy and last ~100 times longer. LED deployment will bring substantial economic and environmental benefits for Australia and globally. Next generation high-efficiency LEDs for lighting, will operate with reduced energy consumption, thus contributing to reaching future national targets for CO2 emission reduction.

The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems. Major difficulties are being encountered in the computation of high-order and correlated terms of Quantum Electro-Dynamical effects in atoms. We will make the first measurements for medium-Z atoms critically sensitive to two-electron QED, and the first tests of QED in this region accurate to 1%.

Quantum plasmas. Quantum effects become important under extreme conditions, and a newly developing field of "quantum plasmas" is motivated by two different extremes for ionized systems. One is in very small electronic devises, where electrons carrying the currents become wave-like with a wavelength comparable with the size of the device. The other is in the extremely intense optical light spots now available by focusing high-power lasers. In this project we propose to take a leading role in the ....Quantum plasmas.
