FIG. 1.

AFM images showing the length changes of nanowires depending on the suspension time in the solution (a) as synthesized, (b) , (c) , (d) , (e) , (f) , and (g) . (h) Time-dependent growth of the length of nanowires at room temperature deduced from the statistics in the characterization.

FIG. 2.

The schematic diagram for preparing the percolating network of nanowires. (a) Preparation of the homogeneously dispersed nanowire solution. (b) Filling the Teflon sample holder with a specific quantity of nanowire solution. (c) Tightening the metal screw with a fixed gap of the capsule space inside the sample holder. The metal screws are connected by electrical wires. (d) Abruptly freezing the sample holder in liquid nitrogen. (e) At a fixed temperature of , the current–voltage characteristics were recorded.

FIG. 3.

Current-voltage characteristics of nanowire percolation system at with aging time. “h” and “d” denotes “hours” and “days,” respectively. Left inset: Slow change of the current with voltage at the early stage of the growth. Right inset: Time dependence of the conductance of nanowires calculated from the linear slope of the current–voltage curves. At around , an abrupt increase of the conductance is observed.
