The effect of a dielectric coating on the near-field radiative heat transfer between two plane surfaces is numerically studied in the framework of the fluctuational electrodynamics. The dielectric coating is assumed to be a SiC or SiO 2 film, which is on top of the emitter. The results show...
Within the work presented here the heat flux was described depending on the geometry and the power density of the IR-emitter and on the so-called view factor which allows the determination of the radiative heat transfer between two surfaces in relative orientation to each other [26]. It was ...
Electrical control of radiative heat transfer between graphene-coated surfaces or between extended graphene and other materials has been also proposed61,62,63,64,65. The competing mechanism (relaxation into phonons) was initially thought to be rather slow in graphene66 (nanosecond scale), a ...
