Abstract

By utilizing a scattering-type scanning near-field optical microscope (s-SNOM) in mid-infrared (mid-IR) region, we studied nanoscale optical and thermal properties of the nanoporous graphene, that is an emerging type of carbon material. Nanoscale IR images revealed that the strained graphene near the nanopores emits less heat radiation, suggesting different absorption mechanism. The present findings provide an interesting possibility of applying this material to high-performance thermal devices such as energy harvester and IR and terahertz devices.
