Bottom-Up Fabricated Asymmetric Electrodes for Organic Electronics

Abstract: A new method for obtaining asymmetric (nano) electrodes through the adsorption and electrochemical desorption of self-assembled monolayers on gold is described. The selective work function modification is demonstrated by Kelvin probe force microscopy and electrical characterization of organic field-effect transistors. The proposed method is simple, fast, and could allow parallel, large-scale fabrication of asymmetric electrodes for micro-and large-area electronics.
