Project TitleTransverse Thermoelectrics
Track Code2011-097
Short Description

A themoelectric technology enabling cooling capabilities below 150K

#materials #semiconductors #electronic


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.
