Quick, Large‐Area Assembly of a Single‐Crystal Monolayer of Spherical Particles by Unidirectional Rubbing

Rubbing a dry powder of particles in one direction between two rubbery substrates is found to be a quick and highly reproducible, yet inexpensive fabrication technique for assembling particle monolayers with perfect spatial registry on flat or curved surfaces. The optimum rubbing conditions – pressure and speed – for a single-crystal monolayer are shown to depend on particle size. Potential applications are in biosensors, photovoltaics, and light manipulators. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
