Abstract: A thermoelectric composite material includes MXene inserted at a boundary of a crystal grain consisting of a thermoelectric material. Accordingly, the thermoelectric composite material may have a reduced thermal conductivity and an increased electrical conductivity. Furthermore, a mechanical property of the thermoelectric composite material may be improved. Thus, the thermoelectric composite material may improve a thermoelectric ability of a thermoelectric module.
