A Simple and Efficient Approach to a Printable Silver Conductor for Printed Electronics

A simple and efficient approach to a printable silver conductor for organic electronics is described. Conductive silver features were prepared by annealing thin-film features deposited from an alcoholic solution of silver acetate, ethanolamine, and a long-chain carboxylic acid. High electrical conductivity similar to that of a vacuum-deposited silver conductor could be achieved at a relatively low processing temperature. Organic thin-film transistors with silver source/drain electrodes prepared by this approach provided excellent field-effect transistor properties.
