Individually Position-Addressable Metal-Nanofiber Electrodes for Large-Area Electronics

A individually position‐addressable large‐scale‐aligned Cu nanofiber (NF) array is fabricated using electro‐hydrodynamic nanowire printing. The printed single‐stranded Cu NF has a diameter of about 710 nm and resistivity of 14.1 μΩ cm and is effectively used as source/drain nanoelectrode in pentacene transistors, which show a 25‐fold increased hole mobility than that of a device with Cu thin‐film electrodes.
