Electronic transport in graphene nanostructures on SiO
... Studies of the temperature dependence of the conductance were reported in Refs. [40,41]. These experiments confirmed the importance of the Coulomb interaction for transport, and found a temperature dependence consistent with Shklovskii–Efros variable-range hopping conduction [42]. However, it is not ...
