在由扫描振动探针/胶体金颗粒/真空/PtPd 基底组成的纳米机械双势垒隧道结构中，观察到由于库仑阻塞引起的位移电流阶梯和隧道电流阶梯。我们讨论了来自隧道和位移电流阶梯的单电子在金粒子上和通过金粒子的运动，并演示了由于纳米机械探针振动而产生的电子穿梭现象。
Displacement current staircase due to Coulomb blockade is observed together with a tunneling current staircase in nanomechanical double barrier tunneling structures that consist of scanning vibrating probe/colloidal Au particles/vacuum/PtPd substrate. We discuss the motion of single electrons on and through the Au particles from both the tunneling and displacement current staircases, and demonstrate the electron shuttle phenomenon due to nanomechanical probe vibration.
