摘要
Thermoelectric effects of Dirac fermions through a van der Waals (vdW) heterostructure consisting of graphene and tungsten diselenide (WS2) are theoretically investigated. When the lattice temperature of the top graphene layer differs from that of the bottom graphene layer, thermally excited Dirac fermions can be transferred through the WS2 layer, generating tunnel current. This thermoelectric tunnel current shows drastic changes in its characteristics as a consequence of gatevoltage tuning. The thermoelectric power of the proposed graphene-WS2 vdW heterostructure is characterized by examining the Seebeck coefficient.
