9. This value does not change significantly if a contact resistance of up to 4 k Ω is taken into account. Our palladium contacts usually have a contact resistance of 1 k Ω or less.
10. Compared to Figs. and, these data were taken after thermal cycling where the CNP had shifted by about 1 V, but the mobility remained unchanged.
11. Here the resistance value exceeds the expected value of 4.3 k Ω since it contains a series contribution of the Pd contacts and the bulk graphene leads, which are also in the quantum Hall regime.
