Summary: Spin Electronics technology will enable a revolutionary class of electronic devices. Gallium nitride (GaN) containing transition metals (TM) (eg Mn, Ni and Fe) is a very promising dilute magnetic semiconductor for practical spintronics applications as this material exhibits magnetic behaviour above room temperature. However, electronic and magnetic properties of this new class of semiconductors have not yet been optimised. This project aims to develop and test a new growth strategy, known as the co-doping method for the fabrication of high quality TM doped GaN. A broad range of complementary advanced spectroscopic techniques will be used to evaluate and refine this new fabrication method.''
