Summary on Grant Application Form |
The development of diamond devices has been seriously hampered by a lack of appropriate bulk dopants which are readily electrically activated. However, under certain conditions diamond displays high p-type surface conductivity even at room temperature and this opens up a new route for the fabrication of high performance active diamond electronics. The present work will explore procedures for the reliable production of surface conductive layers on single crystal and polyCVD material, their metallisation and the fabrication of field effect transistors based on the surface conductive effect.The programme will commence with basic studies of the atomic and electronic structure of diamond surfaces following particular surface treatments, and the correlation with measured surface conductive properties. The aim will be to understand the basic origin of the observed surface conduction properties, and the identification of optimal surface treatment procedures. Subsequent work will involve investigations of the metallisation of these conductive layers and their electrical characterisation, to develop practical processing methods and gain further understanding of electrical properties. The final stage will be to fabricate and characterise the performance of field effect transistor structures based on the surface conductive effect. Implementation of this programme will result in the production of the first surface conductive diamond FETs on polycrystalline diamond, which represents the most commercially realistic diamond material.
