    • Previous transport studies have also shown devices without gaps in the range of gate voltage studied. Observing a gap requires reaching a well-defined charge neutrality point, which may not occur in all devices within the gate voltage range studied because of, for example, doping or disorder

    • Because of the sensitivity of the exponent on the model used and the general difficulty of accurately estimating it, the agreement to theory may be somewhat fortuitous. For example, a recent study gives an alternative scaling exponent of a, 2 for the gap (26, Nevertheless, our data are described both quantitatively and qualitatively by the theoretical calculations of (10, and the exponent of 1.3 is within the range a, 1 2 of theoretically predicted values for all the theoretical works cited that include long-ranged Coulomb interactions 10-12, 26
