▎ 摘　　要

We consider a three slabs configuration including two non-doped single layer graphene (SG) 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 the SG layer, the heat flux is maximum at the Plasmon frequency supported by the G/SiO2 slabs. In the three slabs configuration, the photon heat tunneling is amplified between two G/SiO2 layers significantly, only for a specific range of vacuum gap between the 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 the middle layer, and as a result, it can enable novel applications for nanoscale thermal management.
