My research is primarily concerned with the study of new device, circuit, and fabrication approaches for electronic circuitry that has the potential to surpass the limits of conventional MOS technology. My earliest work has been with the use of GaAs-based and Si-based heterostructures for the development of high-performance complementary heterostructure FET (CMOS-like) circuitry. More recently, my interest has been in the area of the physical mechanisms in ultra-small nanostructure devices.

One topic of special interest is single-electron tunneling phase logic (TPL), in which the electrical phase of a locked single-electron tunneling process is used to represent the logic states in nanometer-scale devices. Another interest is the development of a high-throughput fabrication technology for nanoelectronic devices based on the use of controlled precipitation in a semiconductor to self-assemble nanometer-scale junctions self-aligned to surface electrode patterns.
