From: Control of the near-field radiative heat transfer between graphene-coated nanoparticle metasurfaces
Total heat flux, Q, between GCNP metasurfaces as a function of the chemical potential of the graphene coating, \(\mu\). Purple (pink) dots correspond to GCNPS with cores made of Drude-like material (SiC), while the dashed horizontal line depicts that value of Q calculated for the corresponding homogeneous NP array. The inset of the figure shows the \(\mathscr {T}_p\) coefficient as a function of the normalized frequency \(\omega /\omega _0\) and the longitudinal wavevector \(\kappa /c\omega _0\). In the top (bottom) plots we show the results for two metasurfaces made of Drude-like (SiC) NPs, with the case of homogeneous NPs on the left and the case of GCNPS on the right. In all calculations, \(\text{ PF }=0.5\) and \(R=100\) nm.
