a–e Schematic representation of the translocation events at different voltages from −400 to −800 mV. The frequency of translocation events increased when the applied voltage increased from −400 mV to −800 mV. f The current amplitude linearly increases with the voltage. h An exponentially decaying function (t _d   ~ e ^−v/v0) was employed to fit the dwell time dependent on the applied voltages
