Symmetric Negative Differential Resistance in a Molecular Nanosilver Chain
Figure 4
Capacitance effect of an NSC crystal. (a) A nonzero initial voltage results in the nonexistence of the peak in the voltage region, which is the same sign to the initial voltage. Black and red lines are the voltage sweep with negative and positive initial voltages, respectively. (b) - characteristics were obtained by a consecutive bias voltage sweep. The number shows the sweep procedure.
