Research Description

Professor Junqiao Wu received a B.S. from Fudan University and a M.S. from Peking University, China, both in physics. He obtained a Ph.D. degree in Applied Science and Technology from the University of California, Berkeley for work on nitride semiconductors and highly mismatched semiconductor alloys. He did postdoctoral research in the Department of Chemistry and Chemical Biology at Harvard University on phase transitions in transition metal oxide nanomaterials. He began his faculty appointment in the Department of Materials Science and Engineering at the University of California, Berkeley in 2006. His honors include the Berkeley Fellowship, the 29th Ross N. Tucker Memorial Award, the U.C. Regents' Junior Faculty Fellowship, the Berkeley Presidential Chair Fellowship, the US-NSF Career Award, the US-DOE Early Career Award, the Presidential Early Career Award for Scientists and Engineers (PECASE) from the White House, the Outstanding Alumni Award from Peking University China, the Bakar Faculty Fellows Award, and elected Fellow from the American Physical Society (APS).

The Wu group explores novel properties and applications of strongly correlated electron materials with reduced dimensions, phase transitions at the nanoscale, and optoelectronic, thermal and thermoelectric properties of semiconductor alloys and interfaces.

Researchers create surface coating that can create false infrared images

Light can sometimes play tricks on our eyes. If you look at a shiny surface, what you see will largely depend on the surrounding environment and lighting conditions. Berkeley researchers have now taken ocular distortion a step further, finding a way to imbed visual “decoys” into surfaces of objects in a way that can fool people into thinking they detect a specific image in the infrared that actually isn’t there.

Winner of campus’s new Bakar Prize hopes to harness sun’s power

A few years ago, Junqiao Wu, a UC Berkeley professor of material science and engineering, figured out how he could use thermal power to transform materials: roofs that adapt to temperatures and save energy, new types of sunglasses and even tools that could screen for cancer or monitor hidden defects in buildings.

Smart Materials: Getting the Sun to Pull Down the Shade

When a car seat heats up on a hot day, it just gets.... hot.  But some materials become totally transformed by the sun’s heat. They undergo a kind of Jekyll and Hyde reversal called a phase change. They turn from insulators to metals. Junqiao Wu is exploiting the most remarkable of these compounds, called vanadium dioxide, to devise ways to cool buildings, winter-proof car engines, and even create novel sunglasses.

A Micro-Muscular Break Through

Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add muscle power to its attributes.
