Summary on Grant Application Form |
|
We will construct a custom designed apparatus for the production of high energy plasmatic radicals of fluorine and oxygen, allowing us to oxygenate and fluorinate materials of interest at temperatures considerably lower than those used in conventional solid state synthesis. This novel technique will allow us to investigate the optimal doping levels for known superconductors, both as thin film and bulk materials. We believe that this procedure will allow us to carefully optimise the critical superconducting properties for these materials without recourse to high pressure and temperature post synthesis annealing treatments. Structural determination will be routinely performed through a combination of X-ray diffraction and electron microscopy. We will also use these techniques to determine the nanoscale and defect structures of the as synthesised and plasma treated materials. The surfaces of thin film materials will be analysed, both before and after plasma treatment by atomic force and scanning tunnelling microscopy.Also, we plan to use this technique to oxidise high performance (high Jc, Hirr) thin film and bulk materials, maximising the Tc of these phases. Finally, we plan to perform a series of oxidations and fluorinations on suitably structured non-superconducting materials, with a view to inducing superconducting behaviour in these phases.
