One‐Step Patterning of Aligned Nanowire Arrays by Programmed Dip Coating

Dip, stick, slip: Dip coating, a widely used industrial process for making thin films, is used to align and position nanowires by means of the stick–slip motion of the solvent meniscus. Nanowire arrays with predefined spacing can be readily "printed" on a large substrate with tunable wire density (see picture), thus providing a facile method for producing nanowire-based devices.
