Biography

I obtained my PhD in Cardiff, a Royal Society URF at Oxford ICL and am now Associate Professor of Electron Microscopy in Warwick. I pioneered encapsulation of Extreme Nanowires characterised by high performance electron microscopy, Raman spectroscopy and ab initio modelling with partners in Warwick, Southampton, Nantes, Cambridge and Birmingham. 

My Fellowship

My Fellowship project will involve the spatial and time resolved crystallography, structural refinement and functional evolution of one to four atom thick 1D 'Extreme Nanowires' formed inside carbon nanotubes - atomically smooth templates thermally robust up to 1130ï‚°C. This is a Final Frontier of materials science and the next and lowest dimension relative to two-dimensional structures such as graphene. My project will address their one to three-dimensional crystallography with atom-by-atom sensitivity; heir four-dimensional time-resolved crystallography for the special case of nano-Confined Phase Change Materials, which change properties over a phase transition with potential utility in Non-Volatile Memory; the novel physics of these structures will be studied and their functionality demonstrated in 'Proof of Principle' devices.

This project is expected to play a significant role in techniques development both in Warwick and through the Project Partner network based in Oxford, Vienna, Warsaw, Pau and Beijing. The ultimate scale of the materials under examination will test and improve the most sensitive characterisation methodologies currently available, especially high performance electron microscopy and associated spectroscopic methods, in situ low-temperature imaging, in situ resistance/conductivity measurements, high performance scanning probe microscopies and thin film device fabrication.

I will lead these activities from the UK which can potentially then add 1D nanostructures to its dominance in 2D Nanomaterials by pursuing this complementary but beyond graphene ultimate nanoscale research.

Atomically regulated nanowires represent the last ordered domain of materials after graphene, being only 1-4 atoms in cross-section. My recent EPSRC theory collaboration (EP/M010643/1)) with Quigley (Warwick) and Morris (Birmingham) indicates that the functional potential of these materials is reaching critical mass. These materials also reveal the possibility of investigating phase formation at the smallest volume scale ever attempted. I wished to lead a groundbreaking experimental Fellowship Program that will reveal this functional potential through structural and compositional refinement, perform up to femtoscale time-resolved nanoscale investigations into the phase change characteristics and incorporate these materials into ‘proof of principle’ devices.

My Fellowship Proposal is firstly motivated by the science i.e. the possibility of studying the last orderable domain of materials but the Fellowship will enable me to investigate the potential of these materials much more rapidly. Additionally, this Fellowship has enabled the creation of a new Project Partner network in Oxford, Pau, Beijing, Warsaw and Vienna which should accelerate the dissemination of this research. In leading this project, I anticipate that my own profile and career will develop commensurately. More significantly I anticipate that the UK's lead into ultimate scale nanomaterials will be enhanced and maintained.
