Abstract
Provided herein are a thermoelectric material and a method for preparing the same. The thermoelectric material may include a plurality of grains formed by a chemical bond between a first element and a second element, a graphene-based material; and metal particles. In particular, the graphene-based material and the metal particles may be in interfaces between the grains.
Claims19
A thermoelectric material comprising:
- a plurality of grains formed by a chemical bond between at least a first element and a second element;
- a graphene-based material;
- and
- metal particles,
- wherein the graphene-based material and the metal particles are in interfaces between the grains.
2 more elements
