Near-field Radiative Heat Transfer between Graphene-covered Anisotropic Magneto-dielectric Hyperbolic Materials

The near-field radiative heat transfer (NFRHT) between the anisotropic magneto-dielectric hyperbolic materials (AMDHMs) substrates covered by a monolayer of graphene is theoretically investigated on the basis of the fluctuational dissipation theorem through the scattering method. Unlike that the NFRHT flux between SiC nanowires can be enhanced by graphene coverage, graphene coverages can weakly...

Active thermal extraction of near-field thermal radiation

Radiative heat transport between materials supporting surface-phonon polaritons is greatly enhanced when the materials are placed at subwavelength separation as a result of the contribution of near-field surface modes. However, the enhancement is limited to small separations due to the evanescent decay of the surface waves. In this work, we propose and numerically demonstrate an active scheme t...

Graphene-based photovoltaic cells for near-field thermal energy conversion

Thermophotovoltaic devices are energy-conversion systems generating an electric current from the thermal photons radiated by a hot body. While their efficiency is limited in far field by the Schockley-Queisser limit, in near field the heat flux transferred to a photovoltaic cell can be largely enhanced because of the contribution of evanescent photons, in particular for a source supporting a su...
