Thermometry for Dirac fermions in graphene
We use both the zero-magnetic-field resistivity and the phase coherence time determined by weak localization as independent thermometers for Dirac fermions (DF) in multilayer graphene. In the high current (I) region, there exists a simple power law T DF ∝ I ~0.5 , where T DF is the effective Dirac f...
