Key Points

To investigate how graphene can control near-field radiative heat transfer (NFRHT) in nanometric cavities.
Explored heat transfer across nanometric gaps using graphene.
Analyzed the role of surface polaritons in enhancing heat transfer.
Employed theoretical models to predict NFRHT efficiency.
Demonstrated that NFRHT can exceed the blackbody limit significantly in graphene-enhanced cavities.
Found that the presence of surface polaritons contributes to increased heat transfer rates.

Implication

NFRHT enhances thermal management in nanogaps, indicating potential for more efficient cooling solutions.

Abstract

Near-field radiative heat transfer (NFRHT) across nanometric gaps can surpass the blackbody limit by orders of magnitude via evanescent waves and surface polaritons, offering exciting opportunities for ultra-compact thermal management,...
