Summary on Grant Application Form
Many of the useful properties of crystalline materials are driven by the presence of defects, be they beneficial such as impurities that make semiconductors function, or detrimental such as colour centres and non-radiative recombination channels that degrade optical systems. Diamond has many desirable mechanical, optical and thermal properties, but the production of semiconductor devices has been hampered by the lack of available donor species. The ability to determine theoretically candidate donors is a highly desirable expedient to the eventual manufacture of useful material. The chief aim of this project is to develop an understanding of the limitations and possibilities for the exploitation of various materials for electronic and/or optical applications. I shall employ state-of-the-art quantum mechanical techniques to simulate the properties defects chiefly in diamond, but also in silicon, germanium, SiC, ZnO and GaN. Emphasis will be placed on the evaluation of experimentally observable characteristics, since the modelling is most potent when in tandem with measurement. Theoretical techniques can then be used in a predictive way to engineer defects with the correct characteristics, including the surface effects that are crucial in the growing material for the incorporation of dopants and the removal of unwanted defects.
