Research Interests

Our group focuses on the following studies: 


Unconventional Solar Cell Design, Fabrication and Analysis: Using state-of-the-art materials science and technology approaches, we are constructing one of a kind high efficiency solar cells.

Nanostructured Carbon Sheets, Tubes and Molecules: Recently we developed a technique whereby large quantities of nano-structured carbon materials can be grown at high temperatures. These very high-quality nanomaterials have been used to fabricate flat panel displays and energy-generation and storage devices. 

Photonic crystals: The fabrication of ZnO-based photonic crystals that can also lase has been an important part of the group research. We are currently imbedding quantum dots into these materials to study resonant effects for highly sensitive detection of molecules. 

Amorphous Semiconducting Oxide Films: We have been studying a class of unique complex amorphous oxide films which have high optical transparency and electron mobility. A fundamental understanding of this exotic material system will lead to the development of a new generation of transparent field effect integrated circuits and energy systems. 

Nanostructured Plasmonic Materials in the Infrared: We have started the investigation of 2-D and 3D oxide-based plasmonic materialsfor the purpose of molecular detection and manipulation in the infrared region of the spectrum.  This effort will advance the understanding of molecular chemistry and dynamics.
