Anomalies of the boundary potential of a 2D electron system under Hall quantization conditions
Veselago V. G., Zavaritskii V. N., Nunuparov M. S., Berkut A. B.
In the absence of a steady current in the measuring circuit, the equipotential state of the internal and external contacts of a MIS structure is disrupted under conditions corresponding to the Hall resistance quantization. The MIS structure is arranged in the Corbino geometry. Under steady-state conditions this "topological" potential difference does not change after short-circuiting of the contacts is lifted.
