Research focuses on the development of new chemical vapor deposition techniques for the molecular engineering of thin film structures with specific application to the microelectronic, optoelectronic, and renewable energy sectors. Specific research interests include: (1) pulsed plasma-assisted chemical vapor deposition of oxides and metals; (2) plasma-assisted co-evaporation (PACE) synthesis of photovoltaic absorbers; (3) PECVD of disordered metal oxides; (4) macroscopic modeling of plasma and thermal CVD reactors; (5) understanding the fundamental process-structure-property-performance relationships in these systems.
