Exploratory electronic devices and microfabrication techniques. Pursuit of these interests included work on flat panel display technology, ultrashort-gate-length self-aligned GaAs MESFETs, GaAs and germanium MOSFETs, rapid thermal processing, superconducting FETs, InGaAs/InAlAs SISFETs, ohmic contacts on compound semiconductors, silicon etching and etchstops, and fabricating laser fusion targets by semiconductor microfabrication techniques
