A large percentage of the NWs were serving as current paths between the top and bottom electrodes (Fig. 1D). The resistance introduced by the active NWs was less than 2% of the total resistance, when considering the NWs that were not in contact with the electrodes; thus, it could not produce the large jump in current as observed experimentally.
