Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develo ....Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develop an entirely new information storage system: a high-density silicon phase change memory. This project aims to study small-scale transformation behaviour in silicon and to design demonstrator memory devices based on both micro-electromechanical systems and solid state technologies.Read moreRead less

Australian scientists and engineers require immediate access to frontier T-ray (terahertz radiation) technology to solve pressing current problems in semiconductor nanostructures and emerging problems in fields as diverse as biophysics and national security. Recent innovations now make practical the production of bursts of terahertz radiation by applying ultrafast optical pulses to photoconductive or electro-optic media, facilitating unparalleled time-resolved spectroscopy and imaging. The state-of-the-art equipment to be purchased and installed at Wollongong will enhance the existing excellent terahertz infrastructure (unique spectrometers, optically-pumped molecular laser) and efficiently service researchers in the dynamic Sydney (UTS, UNSW) - Wollongong (UoW) - Canberra (ANU) corridor.Read moreRead less
