Abstract

(Figure Presented) Positive feedback: Relatively large gaps can be reproducibly fabricated by utilizing the change in impedance arising from the high electric field between the electrodes in a feedback-controlled electrodeposition system. Furthermore, the gap size can be finely tuned down to around 1 nm by simply controlling subsequent deposition time (see SEM images).
