Co-doping and transition metal doping of Gallium Nitride. Spintronics is poised to create a new paradigm in device electronics. Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature.

Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science.

For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less

Unconventional topological spin structures at the nanometre scale, such as skyrmions in chiral spin systems, could be used in ultra-low energy electronics and high density data storage. In particular, multi-ferroic skyrmion materials could directly control skyrmions through an external electric field, which makes them ideal for nanoelectronics and data storage for IT applications.
