论文摘要
我们证明了电子量子传输中经典特征的出现，用于扫描栅极显微镜响应，在量子点接触和微米大小的圆形反射器定义的腔中。反射器折叠在二维电子气体上的量子点接触的电子流动特征中的分支，产生了复杂的空间模式。考虑到扫描门尖端对经典轨迹的偏转，可以建立扫描模式的简单关系，这与最近的实验发现一致。
We demonstrate the emergence of classical features in electronic quantum transport for the scanning gate microscopy response in a cavity defined by a quantum point contact and a micron-sized circular reflector. The branches in electronic flow characteristic of a quantum point contact opening on a two-dimensional electron gas with weak disorder are folded by the reflector, yielding a complex spatial pattern. Considering the deflection of classical trajectories by the scanning gate tip allows to establish simple relationships of the scanning pattern, which are in agreement with recent experimental findings.
