Our research is in the physical chemistry of materials, interfaces, nanocrystals, and nanotubes, especially in relation to optical and electronic properties. This work can include theoretical modeling, experimental chemical physics, and synthetic chemistry. We try to understand the size evolution of solid-state properties from molecular properties. We also seek to create new materials with nanoscale structure by both kinetic and thermodynamic self-assembly methods. We specialize in interfacial electron transfer, Electric Force Microscopy and Laser Optical Microscopy for observation of single nano-objects. In the last several years, we have developed interests in transition metal oxide nanocrystals, carbon nanotubes, and in Ag nanocrystals as microscopic antennas for local electromagnetic field enhancement.
