Photons typically do not contribute to thermal transport within a solid due to their low energy density and tendency to be absorbed quickly. We propose a practical material system—infrared plasmonic resonators embedded in a semiconductor nanowire—that leverages near-field electromagnetic coupling to achieve photonic thermal transport comparable to the electronic and phononic contributions. We analytically show photonic thermal conductivities up to about 1 W m−1 K−1 for 10 nm diameter Si and InAs nanowires containing repeated resonators at 500 K. The nanowire system outperforms plasmonic particles in isotropic environments and presents a pathway for photonic thermal transport to exceed that of phonons and electrons. [ABSTRACT FROM AUTHOR]
