Graphene has a high electron mobility at ordinary room temperature. Experiments also has shown that the conductivity of electron and holes are almost the same. Between the temperature 10 to 100 k it is independent of temperature. At room temperature the resistivity is $10 ^{-6}$ ohmcm. There is a good wikipedia article for more information.
