Abstract

Transverse Thermoelectrics NU 2011-097 Inventors Chuanle Zhou, Matthew Grayson Abstract Transverse thermoelectrics are materials that exhibit thermoelectric heat flow transverse to the direction of an applied electrical current. This renders these materials extremely useful for cooling applications. A strategy was developed to engineer band anisotropic transverse thermoelectrics whereby the anisotropic electron and hole mass tensors result in orthogonal electron and hole currents, and a large transverse ambipolar Seebeck coefficient. The intrinsic cooling mechanism can function at cryogenic temperatures, thus promising to fill a gap in thermoelectric cooling capabilities that currently exists below 150 K. Applications o Cooling Advantages o Performance at cryogenic temperature o High efficiency cooling o No need for high magnetic field Publications Utility Patent filed 13/735,373 Marketing Contact Arjan Quist Invention Associate (p) 847-467-0305 (e) arjan.quist@northwestern.edu
