Research Theme: Characterization and Synthesis of Renewable-Energy Materials

Our group uses TEM and related characterization techniques to analyze and control the structures of materials with renewable-energy applications.


Research projects include:

• Lattice-mismatched III-V heterostructures for high-efficiency, multijunction and nanostructured solar cells;

• Solid-phase crystallization of a-Si:H, a-Ge, and a-TiO2 thin films.
