Abstract
Current-voltage phase shift measurements are reported between electrod es situated near the rim of an array located below a charged liquid he lium surface. Data are taken in magnetic fields up to 20 T at a temper ature near 2 K. Under these conditions, the ultra-quantum limit is rea ched, where the Landau level width is larger than the electron thermal energy. Interpreting the data in terms of the AC Hall effect, or edge magnetoplasmon, suggests that the Hall resistivity deviates from its classical value for fields greater than 10 T.
