Carbon Mitigation: Focus Areas
Thermoelectric Cooling Technologies
Our thermoelectric materials are ideal for cooling discrete sensors, optoelectronic devices such as lasers and LEDs, and other electronics. Our thin-film superlattice devices are expected to be significantly smaller (x10) and faster (x100) than commercial state-of-the-art bulk devices, and they can pump heat at much higher power densities. Thermoelectric cooling technologies can be very attractive for achieving highly efficient, localized, and on-demand cooling for a variety of systems, thereby boosting energy efficiency.
