Abstract

A comprehensive analytical system that connects flow pattern, crystallization, and thin-film properties is introduced by Steve Park, Jaewook Nam, and co-workers in article number 2004864. Using 3D-patterned microfluidic channels, flow pattern is precisely manipulated. 3D numerical simulation and in situ microscopy enable tracking of the flow pattern along its entire path, elucidating its relation to the crystallization process. The resulting organic thin-film transistors have superior device-to-device uniformity.
