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.
