Extended Data Fig. 4: Determination of Pt-WSe2 contact resistance.

From: Competition between excitonic insulators and quantum Hall states in correlated electron–hole bilayers

Extended Data Fig. 4

a, Schematic circuit diagram for two different Rh measurement configurations. b, Comparison of the obtained resistances as a function of VB along the CNL, measured at B = 0. Their difference (yellow line) corresponds to the total Pt-WSe2 contact resistance on the two sides. Nearly no VB dependence is observed, with an average value of 2.2 kΩ. c, Magnetic field dependence of the Pt-WSe2 contact resistance, showing a slight increase at high fields.
