Abstract:
1. A process for preparing a nanogap device for measuring changes in electrical properties or electrical responses of a sub-micron sized material, said device comprising: (a) a substrate; and (b) at least one conducting electrode pair separated by a nanogap positioned on or within said substrate, wherein said process comprising: a. positioning a conducting material on a substrate wherein said material has a longitudinal axis which exceeds that of its horizontal axis, wherein said conducting material comprises a second portion of said material along its longitudinal axis, which is thinner than a first portion of said material along its longitudinal axis; b. applying an insulator coating to said conducting material; and c. applying a voltage to said conducting material; wherein application of said voltage results in forming a gap in said second portion and at least partial removal of said insulator coating of said second portion.
