Peidong Yang is an inorganic chemist transforming the field of semiconductor
nanowires and nanowire photonics and enabling wide-ranging practical
applications. Nanowires are very small wires at the nano scale—so small
that they behave differently, with quantum effects. Yang has led major
breakthroughs in nanowire photonics over the last decade, from the initial
development of nanowire lasers to the characterization of optical routing in
nanowire assemblies and nanowire solar cells.
In addition to basic research, Yang has worked toward transitioning nanowire
technology into real-world applications. Technology based on his findings
is now being demonstrated in commercial devices for the conversion of waste
heat into electricity, in chemical sensors, and in optical switches. Yang’s
current research also focuses on artificial photosynthesis. Photosynthesis
is the process by which plants gather sunlight and carbon dioxide from the
air, combine them with water, and store energy in chemical compounds;
previous attempts to replicate it as a means for converting solar energy
into fuel have not been efficient enough for commercial use.
Yang and his collaborators have created a synthetic “leaf” that is a
hybrid system of semiconducting nanowires and bacteria. The nanowires gather
sunlight, and the bacteria trigger the use of carbon dioxide and water to
complete the photosynthetic process and produce a targeted carbon-based
chemical such as butanol. The team’s recent breakthrough in synthesizing
carbon dioxide into methane, the primary component of natural gas, exhibits
the potential to convert solar energy with an efficiency that makes it
viable for commercial use. Yang’s advances in the science of nanomaterials
are opening new horizons for tackling the global challenge of clean,
renewable energy sources.
Peidong Yang received a B.A. (1993) from the University of Science and
Technology in China and a Ph.D. (1997) from Harvard University. He was a
postdoctoral fellow (1997–1999) at the University of California at Santa
Barbara before joining the faculty of the University of California at
Berkeley, where he is currently the S. K. and Angela Chan Distinguished
Professor of Energy and Professor of Chemistry. His scientific papers have
appeared in such journals as Science, Nature, Proceedings of the National
Academy of Sciences, and Journal of the American Chemical Society, among
others.
