Ultra-fast transistors play a decisive role in modern telecommunications and are found in everything from mobile telephones to HD television. The rapid advances in transistor technology and its impact on society has recently been recognised by the award of the 2000 Nobel Prize in Physics for electronic device design. However the rapid advances in technology have reached the stage where unexpected new phenomena are being observed in extremely high quality transistors that cannot be explained by existing theories. This proposal addresses this imbalance and aims to develop powerful theoretical tools to investigate unexplained quantum effects in ultra-high quality transistors.Read moreRead less
STRUCTURAL ANALYSIS OF SILICON ON SAPPHIRE THIN FILMS GROWN USING SOLID-PHASE EPITAXIAL TECHNIQUES. Devices based on silicon-on-sapphire processing are potentially faster and are prepared with fewer processing steps than those based on conventional silicon processing technology. However, silicon-on-sapphire films prepared by traditional methods are unsatisfactory due to the high densities of defects they contain. The development of solid phase epitaxial processing has lead to significant increas ....STRUCTURAL ANALYSIS OF SILICON ON SAPPHIRE THIN FILMS GROWN USING SOLID-PHASE EPITAXIAL TECHNIQUES. Devices based on silicon-on-sapphire processing are potentially faster and are prepared with fewer processing steps than those based on conventional silicon processing technology. However, silicon-on-sapphire films prepared by traditional methods are unsatisfactory due to the high densities of defects they contain. The development of solid phase epitaxial processing has lead to significant increases in performance. This project will characterize the structures of films grown by this new process, and relate them to both the processing conditions and device performance. A greater understanding of the relationship between processing, structure and properties will assist the commercial development of these devices.Read moreRead less

Silicon-based molecular electronics. A whole new class of electronic devices based on single atoms and molecules is emerging. At this scale, the device components cease to behave like ordinary matter and novel quantum effects can be exploited.

A whole new class of electronic devices based on single atoms and molecules is emerging. At this scale, the device components cease to behave like ordinary matter and novel quantum effects can be exploited. The tremendous potential for both device miniaturisation and the exploitation of quantum effects afforded by single-molecule devices has already been demonstrated. However, methods for assembling single-molecules into circuits and integrating them with conventional technology remain elusive. Here, a strategy is presented for combining the functionality of organic, carbon-based components, with more conventional, silicon-based technology. The potential economic benefits for Australia of this hybrid carbon/silicon strategy are huge.Read moreRead less
