METHOD FOR FABRICATING NANOGAP ELECTRODES, NANOGAP ELECTRODES ARRAY, AND NANODEVICE WITH THE SAME

摘要

A substrate 1 having metal layers 2A and 2B arranged to form a gap is dipped in an electroless plating solution mixed an electrolyte solution including metal ions with a reducing agent and a surfactant. Metal ions are reduced by the reducing agent to be precipitated on the metal layers 2A and 2B, and the surfactant is adhered to a surface of the metal on the metal layers, thereby forming a pair of electrodes 4A, 4B to be controlled to have a nanometer sized gap. These steps enable to provide a method for fabricating nanogap electrodes, a nanogap electrodes array, and a nanodevice with the same.
