WebJul 12, 2007 · The conductivity of graphene samples with various levels of disorder is investigated for a set of specimens with mobility in the range of cm /V sec. Comparing the experimental data with the theoretical transport calculations based on charged impurity scattering, we estimate that the impurity concentration in the samples varies from cm. WebApr 9, 2010 · Thus, graphene may help in applications such as conducting heat away from electronic circuits. Abstract The reported thermal conductivity (κ) of suspended graphene, 3000 to 5000 watts per meter per kelvin, exceeds that of diamond and graphite. Thus, graphene can be useful in solving heat dissipation problems such as those in …
