The current research is involved with the deposition and study of semiconductor films. Thin films of silicon carbide with the addition small amounts of germanium are the basis of one study. A new thrust of this research is the growth of graphene, single atomic layer graphite. This work is supported by AFOSR with additional assistance in measurements from ARL in Adelphi, MD. Collaboration with researchers at the University of California Los Angeles has begun on the graphene project.
Another project is the study of chalcopyrite thin films for solar cell applications. The concentration of this work has been on copper-indium-diselenide with the substitution of small amounts of gallium, aluminum, or boron for some of the indium in order to create higher bandgaps for a closer match to the solar spectrum at the earth's surface. This work is supported by DOE and NRI. An additional material, iron sulfide is also under study. Collaboration of long standing is with colleagues at the University of Nebraska at Kearney.
Support for the iron sulfide and the new tin sulfide is from the Nebraska Center for Energy Sciences Research.
