Woochul’s work on “ultralow thermal conductivity in all-inorganic halide perovskites” has been highlighted in LBNL News Center, titled “A Semiconductor That Can Beat the Heat“.
A newly discovered collective rattling effect in a type of crystalline semiconductor blocks most heat transfer while preserving high electrical conductivity – a rare pairing that scientists say could reduce heat buildup in electronic devices and turbine engines, among other possible applications.
Letian, Minliang and Chris’ work has been highlighted in LBNL online News Center, titled New Class of ‘Soft’ Semiconductors Could Transform HD Displays. “Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites is capable of emitting multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers.”
Woochul will join University of Hawaii at Manoa as an assistant professor. Congratulations!
Peidong gave a talk on Cal Future Forum sharing the solutions for a sustainable future where he gave the audience a glimpse into the potential of artificial photosynthesis, a way to create renewable energy that doesn’t cause a net release of carbon dioxide into the atmosphere. The technology, he said, can transform carbon dioxide and water into chemical fuels using sunlight.

Letian, Andrew, and Yi’s paper highlighted by LBNL News: “Researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have successfully grown atomically thin 2D sheets of organic-inorganic hybrid perovskites from solution. The ultrathin sheets are of high quality, large in area, and square-shaped. They also exhibited efficient photoluminescence, color-tunability, and a unique structural relaxation not found in covalent semiconductor sheets.”
Peidong, along with Thomas Moore and Ted Sargent, was interviewed by the Kavli Foundation and livescience on bacteria-nanowire work. “By marrying nanoscience and biology, Yang and his colleagues created a biologically inspired, but completely artificial, system that converts the sun’s rays into fuel and chemicals. The system uses long, nanoscale filaments to turn sunlight into electrons, which bacteria use to convert carbon dioxide and water into butanol fuel and more complex molecules such as acetate, a chemical building block, and amorphadiene, which is used to make antimalarial drugs.”
Joint project with Prof. Chris Chang and Prof. Michelle Chang “…has now developed a hybrid system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.”

Bin’s paper highlighted by Photonics.com:
” A flat mesh of light-absorbing semiconductor nanowires can split water molecules, producing hydrogen gas that could be used for fuel….The mesh works without any electron mediators. The researchers said that large-scale networks of the mesh could be made using low-cost solution synthesis and vacuum filtration techniques. The hydrogen created by these mesh networks could fuel vehicles and power homes and businesses in an environmentally friendly way.”

The company’s first product, called the E1, attaches to an exhaust stack and uses Alphabet’s patented thermoelectric materials to convert waste heat into electricity. Thermoelectrics use a temperature differential to generate electricity in the solid state. This product introduction is the first for the company, which was founded in 2009 at Lawrence Berkeley National Laboratory.”
