Abstract
Embodiments are notably directed to a thermoelectric device including a thermoelectric element. The thermoelectric element includes a Weyl semimetal and a plurality of magnetized elements. The plurality of magnetized elements are configured to apply a directed magnetic field on the Weyl-semimetal. Embodiments further concern a related method for cooling a device and a related method for generating electrical energy.

A thermoelectric device comprising a thermoelectric element, the thermoelectric element comprising a Weyl semimetal and a plurality of magnetized elements, the plurality of magnetized elements being configured to apply a directed magnetic field on the Weyl-semimetal.
A method for cooling a device, the method comprising:
- providing a thermoelectric device comprising a thermoelectric element, the thermoelectric element comprising a Weyl semimetal and a plurality of magnetized elements;
- applying, by the thermoelectric device, an electrical current to the thermoelectric element;
- applying, by the plurality of magnetized elements, a directed magnetic field on the Weyl-semimetal, the directed magnetic field being applied in parallel to the direction of the electrical current;
- and
- generating a heat flux through the thermoelectric element in response to the electrical current.
A method for generating electrical energy, the method comprising:
- providing a thermoelectric device comprising a thermoelectric element, the thermoelectric element comprising a Weyl semimetal and a plurality of magnetized elements;
