Abstract
A transverse thermoelectric device includes a superlattice body, electrically conductive first and second contacts, and first and second thermal contacts. The superlattice body extends between opposite first and second ends along a first direction and between opposite first and second sides along a different, second direction. The superlattice body includes alternating first and second layers of crystalline materials oriented at an oblique angle relative to the first direction. The electrically conductive first contact is coupled with the first end of the superlattice and the electrically conductive second contact is coupled with the second end of the superlattice. The first thermal contact is thermally coupled to the first side of the superlattice and the second thermal contact is thermally coupled to the second side of the superlattice. A Seebeck tensor of the superlattice body is ambipolar.
