Enhanced Near‐Field Radiative Heat Transfer between Graphene/hBN Systems (Small 19/2022)

Abstract

Radiative Heat Transfer In article number 2108032, Jinlin Song, Zixue Luo, Qiang Cheng, and co-workers measure the near-field radiative heat transfer between graphene/hexagonal boron nitride systems, where the coupling of hyperbolic phonon polaritons and surface plasmon polaritons is examined. The largest ever radiative heat flux is achieved for a gap space of ≈400 nm, which is six times higher than the blackbody limit.
