Enhancing the performance of high voltage direct current power cables by studying space charge accumulation in their synthetic polymeric insulation. Synthetic polymeric insulation has proved very successful in high voltage alternating current power transmission cables, and cable manufacturers have therefore sought to use it in high voltage direct current (HVDC) cables, for which there is a rapidly growing demand.

Synthetic polymeric insulation has proved very successful in high voltage alternating current power transmission cables, and cable manufacturers have therefore sought to use it in high voltage direct current (HVDC) cables, for which there is a rapidly growing demand. Yet the accumulation of space charge in such cables presently severely limits the maximum operating voltage and transmitted power. Nearly all this space charge is due to the temperature gradient in the insulation. We will analyze space charge profiles in polyethylene and other synthetic polymers, and derive basic scientific data which will inform the design of HVDC cables with greatly enhanced performance.Read moreRead less
Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals. Knowledge of the detailed shape of the Fermi surface of a conducting material is vital for an understanding of its electrical and magnetic properties. We will use angle resolved photo-emission in conjunction with synchrotron radiation to explore the Fermi surfaces of technologically important magnetic alloys, the mechanism driving the occurance of charge density waaves in layer compounds and the electron ....Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals. Knowledge of the detailed shape of the Fermi surface of a conducting material is vital for an understanding of its electrical and magnetic properties. We will use angle resolved photo-emission in conjunction with synchrotron radiation to explore the Fermi surfaces of technologically important magnetic alloys, the mechanism driving the occurance of charge density waaves in layer compounds and the electronic properties of wide band-gap semi-conductors such as GaN, SiC and of selected quasi crystals. These measurements will be performed using a unique high resolution toroidal spectrometer currently under construction at La Trobe university.Read moreRead less
Search for spin liquids and novel physics of strongly correlated electrons. This project aims to identify new physics in quantum magnets and emergent phenomena in solids where the electrons are strongly coupled and intertwined in a complex manner. As a consequence, quantum effects are dramatically enhanced and, in certain situations, force the electrons to split into different exotic particles.

It will demonstrate a new category of ferroelectric material. By combining it with other materials like graphene, it will realise fully two-dimensional and completely new conceptual devices that are capable of preserving information in a non-volatile manner and performing non-destructive information readout. The outcomes will significantly enhance the information density, stability and readout protocols. Successful demonstration of non-destructive readout provides a key conceptual step forward for the ferroelectric random-access memory to be widely used as a universal computing memory and provides fundamental support for the electronic industry.

Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate.

Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic donors, aiming for spin-free and thus noise-free dopant properties. This should provide significant benefits to defence capability, through enhanced magnetic anomaly detection in naval environments, and health outcomes, through neural sensing of brain signals at room temperature.Read moreRead less
