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
Mapping electronic structure and material properties with atomic resolution. This project will use electron energy loss spectroscopy (EELS) to map the bonding and electronic structure of InGaN quantum wells at the atomic scale. We will measure and correlate the local composition, strain and electronic structure variations within the wells in order to understand the optical emission in this system. The characterisation tools developed will allow us to go beyond measuring structure and composition ....Mapping electronic structure and material properties with atomic resolution.

The fabrication of ordered structures at the nanometre scale is essential if the aspirations of nanotechnology are to be achieved. Understanding the fundamental nanoscience controlling the fabrication and operation of such devices is vital. The combination of instruments requested for this project will allow the construction of arrays of nanoparticles, their precise characterisation and the direct measurement of interpartice and intermolecular forces at the pN level. Parallel computational chemistry and state of the art experiments will lead to the optimised design of nanostructures that will be applied in diverse areas, including mineral processing, biosensors, photonics, magnetic storage and catalysis.Read moreRead less
Quantum dynamics of solid-state qubits. The primary aim of this project is to carry out a critical assessment of several solid-state qubit systems and quantum logic gate operations through detailed theoretical calculations. This project will address important issues such as precise control of electron flux and spin interactions, optimal operating conditions, errors due to imperfection in the system and possible mechanisms for error elimination, as well as reliable measurements of the output qubi ....Quantum dynamics of solid-state qubits. The primary aim of this project is to carry out a critical assessment of several solid-state qubit systems and quantum logic gate operations through detailed theoretical calculations. This project will address important issues such as precise control of electron flux and spin interactions, optimal operating conditions, errors due to imperfection in the system and possible mechanisms for error elimination, as well as reliable measurements of the output qubit register. In addition, qubit systems have shown themselves to be tiny laboratories in which fundamental concepts in quantum mechanics can be tested and a new regime of physics can be learnt.Read moreRead less

The limits of miniaturisation using current technology are rapidly being reached, and the next stage is in the realm of nanotechnology. The goal of the field known as molecular electronics is to reach the point where electronic components are composed of single molecules or single molecular layers. In this field the smallest active component is the molecular diode, and this project is focussed on achieving practical performance from molecular diodes, as a crucial first step in achieving miniaturisation far beyond anything now possible.Read moreRead less
