James J. and Carol L. Shuttleworth Professor of Mechanical Engineering, by courtesy in Electical and Computer Engineering
Engineering Thermophysics, University of Science and Technology of China, B.E. - 1989; ME, UC Berkeley, M.S. - 1991; ME, UC Berkeley, Ph.D. - 1994
1. Energy transfer in nanoscale energy conversion materials, including nano-particle/quantum dot, nanowire, thin film, and superlattice thermoelectric and photovoltaic materials. 2. Ultrafast optics, fundamentals of ultrafast light-matter interactions. 3. Nano-optics (near-field optics), field concentration and enhancement at nanoscale, e.g., using nanoscale optical antenna. 4. Ultrafast and nanoscale optical diagnostic methods for investigation of energy transfer processes in nanomaterials. 5. Laser-based micro- and nano-manufacturing, including parallel nanolithography, nanomaterials growth, and laser fabrication of MEMS.
Prof. Xu's group develops advanced ultrafast optical and nanoscale optical technologies and apply them in (1) energy transfer study and (2) development of advanced manufacturing methods.
