The mechanical characteristics of nanocrystals determine the viability of many novel applications and devices emerging from the field of nanotechnology. Despite their fundamental importance, the mechanical properties of these nanocrystals is only vaguely understood, because their size has prohibited their measurement. In this project, we shall investigate the mechanical properties of these materials for the first time using a combination of theoretical modelling, atomic force microscopy, and a new form of spectroscopy that allows the actual deformation of nanocrystals to be measured. The fundamental scientific knowledge gained is expected to impact on the development of current and future nanodevices.Read moreRead less
Spectroscopy of Single Quantum Dots. Colloidal semiconductor quantum dots are materials with promising applications in flat panel displays, biosensors, quantum dot lasers, and optical communication elements.

Colloidal semiconductor quantum dots are materials with promising applications in flat panel displays, biosensors, quantum dot lasers, and optical communication elements. Many of the applications are novel and require firm understanding of the physical and chemical properties of quantum dots to optimise reliability and performance. To fulfil the technological promise of fluorescent quantum dots, problems relating to quantum yield and photostability urgently need to be resolved. These issues will be addressed through spectroscopic studies of single quantum dots both in vacuum and in condensed phases. Ultimately, the findings will guide rational design of nanoscale devices based on quantum dot luminescence.Read moreRead less

The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users. A vibrant and productive facility requires a transparent interface between the scientist and the technology. This Network will set up the communication channels within the user base, and between the users and the facility development program.Read moreRead less

This project aims to develop a voltage sensor that may ultimately be used to measure neuronal signals noninvasively in real-time and over hours. The project expects to generate the fundamental science needed to use nanodiamonds for fluorescence-based voltage sensing that can be easily measured using optical microscopy. The expected outcome is a biocompatible sensor that should provide a solution to one of the biggest challenges in neuroscience; the fast, precise and long-term measurement of neuronal activity. This technology may one day inform our understanding of how the normal brain works and provide major insights into mental health conditions and neurodegenerative diseases.Read moreRead less

This project will develop a robust technique for the quantitative real-time imaging of high-temperature superconductors. The image-analysis algorithm so obtained will be a virtual software lens, which is able to decode the information contained in data obtained by a well-established but hitherto qualitative imaging technique. We will transform this technique into one uniquely capable of obtaining two-dimensional movies of the current distributions, magnetic fields, and pinning defects in superconducting films. Such a quantitative characterization of these key superconductor parameters will be an important tool in the present global quest for room-temperature superconductivity.Read moreRead less

This project aims to develop the hydrogen-terminated surface of diamond as a new semiconducting platform for carbon-based spintronics. It will build upon recent experimental advances that have shown diamond to possess a two-dimensional (2D) hole-based system with strong spin-orbit coupling. As a semiconductor with unique spin properties, surface conducting diamond offers considerable advantages over other 2D materials such as graphene and topological insulators. These unique properties will be exploited to realise novel semiconductor device architectures for the manipulation of spin using electric fields, and for the study of new spin transport phenomena and quasiparticle excitations at semiconductor-superconductor interfaces.Read moreRead less
