Director, Notre Dame Nanofabrication Facility
Directed a program of research in electronic devices and materials. Investigating quantum devices based on Quantum Cellular Automata (QCA), developing these devices using metal tunnel junctions, molecules, and Si/SiGe heterojunctions. Supervised the first experimental demonstration of a QCA cell, line of QCA cells, and majority logic gate. Investigating the fabrication of extremely low capacitance tunnel junction in electrometers for molecular QCA cells, as well as for high-temperature nanostructures. Developed, in collaboration with faculty in the departments of Electrical Engineering and Computer Science and Engineering, a sequence of undergraduate courses, which span the design, fabrication, and testing of an integrated circuit. As director of the Notre Dame Nanofabrication Facility, oversaw extensive upgrades and modernization of the facilities.
Visiting Associate Professor, Department of Electrical Engineering, University of New South Wales, Sydney Australia
Worked with students developing a process to fabricate silicon-based single electron transistors.
Senior Scientist, Galileo Electro-Optics Corporation, Sturbridge, MA
Responsible for the development of dry-etch processes for advanced technology micro-channel plates. Tasks involved the etching of high aspect ratio structures up to 40-100 microns deep in quartz, silicon, gallium arsenide, and silicon carbide.
Post-Doctoral Associate, Cornell University, Ithaca, NY
Investigated ballistic electron transport in one and two-dimensional electron gases. Designed experiments to study the scattering of electrons in a ballistic constriction and a two-dimensional electron gas. Fabricated split-gate devices as small as 0.1 micron using e-beam lithography. Developed a process using PMMA as an interlevel dielectric for multilevel structures with features as small as 30 nm.
Research Assistant, University of California, Santa Barbara, CA
Studied ballistic transport in quantum wires. Developed a two-dimensional Poisson-Schrödinger simulation program to design a structure optimized for high temperature performance. One and two-dimensional Poisson-Schrödinger simulations programs released as freeware, currently used by more than twenty research groups around the world. Fabricated and tested GaAs/AlGaAs devices at near liquid helium temperatures. Designed, fabricated, and tested circuits based on GaAs/AlGaAs heterostructure Direct Coupled FET Logic, including static RAM, frequency divider, and domino logic.
