Figures

Image of FIG. 1.
FIG. 1.

Current through the nanogap for an ac voltage (sinusoidal curve) of frequency (a) 0.01 Hz and (b) 10 Hz, having peak value of 80 V and 90 V, respectively. Inset in (a) shows the current (in units of 10−10 A) during t = 40–60 s.

Image of FIG. 2.
FIG. 2.

Peak current Imax corresponding to the peak value of the applied ac voltage plotted against the frequency.

Image of FIG. 3.
FIG. 3.

Theoretical fit of the experimental data of Fig. 2 at three different voltages of 20 V (lowermost set), 50 V, and 90 V (uppermost set) using Eq.(5).

Tables

Generic image for table
Table I.

Current Io and critical frequency fc as determined by fitting the data of Fig. 2 for different peak voltages Vmax with the expression of Eq. (5).
