Abstract
The temperature dependence of the mesoscopic conductance fluctuations is investigated for disordered graphene. The fluctuations are generated by varying either magnetic field or carrier density (via a back-gate). Very different temperature cut-offs are found for these two types of fluctuations, with the density-induced features persisting to much higher temperatures (beyond 100 K, even) than those observed when sweeping magnetic field. The robust character of the density-dependent fluctuations may cause them to play an important role in determining the operation of future graphene nanodevices, particularly as device sizes are reduced to the nanoscale.
