Thermal conductivity of graphene in Corbino membrane geometry
Abstract
Local laser excitation and temperature readout from the intensity ratio of Stokes to anti-Stokes Raman scattering signals are employed to study the thermal properties of a large graphene membrane. The concluded value of the heat conductivity coefficient ~ 600 W/m · K is smaller than previously reported but still validates the conclusion that graphene is a very good thermal conductor.
