Abstract

Thin film superlattice (SL) based thermoelectric (TE) devices offer the potential for improved efficiency and high heat flux cooling over conventional bulk materials. We have demonstrated external cooling of 55K and heat pumping capacity of 128 W/cm² in single couples and temperature differences as high as 102K in three stage cascade structures. The high heat flux pumping capacity of these in thin film devices are also attractive for hot-spot cooling in electronics. These same materials have also been successfully employed in power generation and energy harvesting applications. In this presentation, we will discuss recent RTI advances in Bi₂Te₃-based thin-film SL (TFSL) devices for cooling and energy harvesting applications.
