Hall effect induced phase shifts in a capacitively coupled two-dimensional electron gas

The influence of the Hall effect on current-voltage phase shift measurements is reported for the capacitively coupled two-dimensional electron gas on liquid helium. The frequencies are low enough that phase shifts due to edge mode propagation are negligible. The Hall effect typically leads to a decreasing phase shift with increasing magnetic field, as a result of the tendency to make the entire edge of the electron sheet an equipotential- (and equiphase) line.
