在本文中，我们提出了一个一般的图片中看到的电导跨越量子霍尔跃迁的量子反点的共振结构的周期性变化。该周期开始于低于ne 2/h平台的共振峰，然后在（n+ 1）e2/h平台下出现一个周期较短的正弦振荡，并在（n+ 1）e2/h平台下出现共振峰.对于连续的转换，循环重复。我们提供了一个解释这种行为的边缘状态模型，并通过数值计算表明，这张照片详细说明了实验观察到的线的形状和依赖关系。
In this paper we present a general picture of the cyclic change in resonant structure seen in conductance across quantum Hall transitions in quantum antidots. The cycle begins with resonant dips below the ne 2/h plateau, which evolve into resonant peaks above it. A sinusoidal oscillation, of shorter period in magnetic field, then appears, which evolves into resonant dips below the (n+ 1) e 2/h plateau. The cycle repeats for successive transitions. We provide an explanation for this behavior in terms of the edge-state model and show by numerical calculation that this picture accounts in detail for the line shapes and dependencies observed experimentally.
