Abstract
The influence of the Hall effect on current-voltage phase shift measur ements is reported for the capacitively coupled two-dimensional electr on gas on liquid helium. The frequencies are low enough that phase shi fts due to edge mode propagation are negligible. The Hall effect typic ally leads to a decreasing phase shift with increasing magnetic field, as a result of the tendency to make the entire edge of the electron s heet an equipotential- (and equiphase) line.
