Abstract

Polariton manipulations introduce novel approaches to modulate the near-field radiative heat transfer (NFRHT). This theoretical investigation centers on NFRHT in graphene-covered Weyl semimetals (WSMs). The findings indicate variable heat-flux enhancement or attenuation, contingent on the chemical potential of graphene. Enhancement or attenuation mechanisms stem from coupling or decoupling of surface plasmon polaritons in the graphene/WSM heterostructure. The graphene-covered WSM photon-tunneling probability variation is analyzed in detail, suggesting methods for actively controlling NFRHT.
