My interests are in the physics of materials. Materials have been the enabling technology for many revolutions in the history of the world. Witness the impact of metals, plastics, and most recently silicon and consider how our lives have been changed by our ability to make, fashion, and transform materials for specific applications. My specific interest lies in the development of new electronic materials capable of operating in harsh, corrosive environments, and materials suitable for very bright flat panel displays (such as those used in lap-tops). Such materials include diamond and the newly developed galium nitride which is the basis of blue lasers.
A natural outgrowth of this interest in materials is the challenge to construct a quantum computer based on the controlled placement of single P atoms in a silicon matrix, and the development of techniques to image these nanostructures using scanning probe microscopies and other techniques.
My key research interests include
- Fabrication of quantum computer architectures using ion implantation techniques.
- Interaction of ion beams with materials studied at the atomic level using scanning probe microscopies.
- Synthesis, characterization and modification of carbon allotropes, including diamond.
- Fabrication and characterization of carbon nanostructures via ion implantation.
- UV Raman Microscopy and near field microscopy.
- UHV Scanning Probe Microscopy of Advanced Materials.
- Fabrication of materials using pulsed laser deposition techniques.
