摘要
We investigated the ac quantum Hall effect of several GaAs-based samples. The influence of temperature, current, and frequency was measured for the plateaux i = 2, Some measurements of the plateaux i = 4 were performed to determine the scaling behavior with respect to i, The observed relations tan be described by simple formulas which provide some insight into the at quantum Nail effect.
