Abstract

We present results from measurements of ultrafast thermal transport in Graphene. We find that on picosecond time scales and 5-20 micron length scales hot carriers, instead of the phonons, are the dominant carriers of thermal energy. The thermal transport is found to be diffusive with a diffusivity of ~500 cm2/s.
