我们证明了通过外部电信号控制原子尺度机械装置的可行性。在锗衬底上,通过用扫描隧道显微镜尖端直接注入原子的电子引起原子对的切换运动。通过精确控制尖端电流和距离,我们使两个原子对的行为就像一个原子大小的弹球机的鳍状肢。这个原子尺度的机械装置展示了六种不同的配置。
We demonstrate the feasibility of controlling an atomic scale mechanical device by an external electrical signal. On a germanium substrate, a switching motion of pairs of atoms is induced by electrons that are directly injected into the atoms with a scanning tunneling microscope tip. By precisely controlling the tip current and distance we make two atom pairs behave like the flippers of an atomic-sized pinball machine. This atomic scale mechanical device exhibits six different configurations.
