Studying thin films with spectroscopic ellipsometry from the terahertz to the ultraviolet
The unifying theme to my research is optical measurement and modeling, typically of thin films.  Although not exclusively, I often study materials relevant to solar cells and full solar cell devices themselves.

Research Highlights
Fabrication conditions affect optical properties in CdS:O solar cell window layers.  (read more)
Use of millimeter wavelengths to measure difference in conductivity across versus along carbon nanotube films.  (read more)
Detection of depth profiles in thin films using real-time measurements during fabrication.  (read more)
