Thin-film transistors in print

摘要

Electronic printing devices that make use of semiconducting 'ink' are a promising route to cheap, large-area and flexible electronics, but such devices generate relatively poor crystallinity in the printed material. Minemawari et al. have developed an inkjet-based printing technique that involves controlled mixing on a surface of two solutions -the semiconductor (Q-BTBT) in a solvent and a liquid in which the semiconductor is insoluble. This antisolvent crystallization technique generates thin semiconductor films with exceptionally high and uniform crystallinity. InkJet printing of single-crystal films H Minemawari etal.
