Weaver Distinguished Professor
Our research interests are in the area of the thin film synthesis. Deposition
techniques include plasma-enhanced chemical vapor deposition (PECVD),
CVD, sputtering, and electrodeposition. A central theme is developing
novel processing techniques that impart nanoscale control while retaining
high rate for the efficient synthesis of mesoscale structures (50 - 1000
nm). Thin films are ubiquitous in advanced technology, and the materials
we synthesize serve as integral components in photovoltaics, membranes,
opto-electronics, electrochromics, thin film batteries, functional coatings,
and catalysis. Investigation of these deposition processes is guided by
detailed reactive flow modeling and experimental measures of both gas-phase
and surface kinetics. In-situ process diagnostics and ex-situ materials
characterization are used to gain a fundamental understanding of the process–structure–performance
relationships in these systems.
