Figure 5.
Visualization and electrical performance evaluation of the fabricated nanochannels. Micro/nanofluidic system when (A) no external electric field was applied and (B) a sufficient electric field that triggers ICP was applied. (C) Current–voltage response of the nanochannels with three different nanostructure pattern widths. The colored voltage sections indicate the section when an ICP phenomenon occurs without the overlimiting current.
