摘要：

We have studied the conductivity peak in the transition region between the two lowest integer quantum Hall states using transmission measurements of edge magnetoplasmons. The width of the transition region is found to increase linearly with frequency but remains finite when extrapolated to zero frequency and temperature. Contrary to prevalent theoretical pictures, our data do not show the scaling characteristics of critical phenomena. These results suggest that a different mechanism governs the transition in our experiment. [S0031-9007(98)07743-6].
