Scientists Grow Thermoelectric Cobaltate Thin Films on Silicon Thin films made of so-called thermoelectric materials could be used to convert heat directly into electric energy, or vise versa, for a variety of applications, including micro-chip-based chemical and biological sensors and more-efficient ways to cool computer chips. Thermoelectrics also hold promise for clean-energy generation because they transform heat into electrical energy without producing carbon dioxide or other emissions.
