Light-Induced Patterned Self-Assembly Behavior of Isotropic Semiconductor Nanomotors.

The self-assembly of nanomotors is important for the production of materials with functional optical, mechanical and conductive properties. Yet, self-assembly methods are limited by their slow kinetics and limited scale. Here we report a light-induced method that yields a large-scale predefined pattern constructed by self-organization of nanomotors. The propulsion mechanism has been analyzed to create a matched experimental device, and numerical simulations are used to explore the dynamic energy-conversion processes. We propose a sizable template fabricating method, which paves the way for new possibilities in surface science.
