Nanostructuring for Efficient Energy Conversion

The chemical and electronic properties of a material can be altered by functionalizing its surface.  At the nanometer size scale in particular, surface and interfacial properties dominate the behavior of devices, and control of these interfaces is critical.  This talk will describe ways to modify semiconductor surfaces through both reactive chemical attachment and molecular self assembly.  Studies in which the properties of semiconductor surfaces are controlled to achieve improvements in energy conversion devices will be presented.
