(color online) (a) Time evolution of voltage of the sample for long slit length at and . (b) Dependencies of the amplitudes (blue dashed–dotted line, left axis), (black dashed line, left axis) and frequency (red solid line, left axis) on the applied current density for the slit with length at . (c) The same parameters as panel~(b) but for the slit with length . The vertical dashed lines are plotted for indicating the transition point.
