4 pages, 3 figures ; International audience ; 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 κ ~ 600 W/m ⋅ K is smaller than previously reported but still validates the conclusion that graphene is a very good thermal conductor.
