Fig. 2: Hall resistivity in low magnetic fields and thermal broadening at the NP.

From: Extreme electron–hole drag and negative mobility in the Dirac plasma of graphene

Fig. 2

a Examples of RH(n) at different T (color coded). b Characteristic width of the region where both electrons and holes are present. Symbols: δnH and δn extracted from the Hall and longitudinal resistivities, respectively. Error bars: standard deviations. Blue curves: δnH(T) expected from the standard Drude model that ignores electron–hole drag.
