B.S. in Chemical Engineering, University of California Berkeley, 1998Ph.D. in Chemical Engineering, Princeton University, 2004
Research Interests:
Our research is focused on organic semiconductors, organic-inorganic hybrid materials and nanocomposites geared toward efficient energy conversion. We study the physical properties of these materials and apply this knowledge to solid state device design and fabrication. In particular, devices of interest include transistors, LEDs, solar cells, memories, near-field optical microscopy probes, and others. As an integral part of this work, we develop novel techniques for organic semiconductor processing, including large-area vapor-phase deposition, high-resolution direct patterning (solvent-free printing), molecular self-assembly, and a range of the more traditional nano- and microfabrication methods.One of the key challenges is to preserve the molecular-level order in the process of fabricating organic electronics on various large-area substrates at low-cost (e.g. low-cost, lightweight solar cells). The work requires the expertise from several disciplines, including chemistry, materials characterization, semiconductor device physics, semiconductor processing, chemical engineering, and many others. The areas of potential impact range from alternative energy technologies, to chemical catalysis, to biotechnology, and even quantum computing.
