Graphene-based three-body amplification of photon heat tunneling

Abstract

We consider a three slabs configuration including two non-doped single layer graphene on insulating silicon dioxide (G/SiO2) substrates and one non-doped suspended single layer graphene (SG). The suspended layer is placed between two G/SiO2 layers. Without SG layer, the heat flux has maximum at Plasmon frequency supported by the G/SiO2 slabs. In three slabs configuration, the photon heat tunneling is amplified between two G/SiO2 layers significantly, only for specific range of vacuum gap between SG layer and G/SiO2 layers and Plasmon frequency, due to the coupling of modes between each G/SiO2 layer and SG layer. Since, the SG layer is a single atomic layer, the photon heat tunneling assisted by this configuration does not depend on the thickness of middle layer and in consequence, it can enable novel applications for nanoscale thermal management.
