摘要: All matter at finite temperatures emits electromagnetic radiation due to the thermally induced motion of particles and quasiparticles. Dynamic control this could enable design novel infrared sources; however, spectral characteristics radiated power are dictated by energy density emissivity, which ordinarily fixed properties material temperature. Here we experimentally demonstrate tunable electronic blackbody emission from graphene plasmonic resonators on a silicon nitride substrate. It is shown that produce antenna-coupled radiation, manifests as narrow peaks in mid-infrared. By continuously varying nanoresonator carrier density, frequency intensity these features can be modulated via an electrostatic gate. This work opens door for future devices may timescales beyond limits conventional thermo-optic modulation.
