An Osaka University research team has created a thermoelectric material with promising performance at room temperature. The non-toxic, room-temperature thermoelectric material is competitive with conventional bismuth telluride, and could be used for power generation or refrigeration. Thermoelectric (TE) materials could play a key role in future technologies. Although the applications of these remarkable compounds have […]

A thin film of bismuth telluride (Bi2Te3) on top of gallium arsenide (GaAs) converts heat into electricity or electricity to cooling creating cooling devices for electronics or generating electricity from heat sources. For years, researchers have developed these thin films and while they knew it could be done, it was not clear how, because the […]
