Controlled Deposition of a High-Performance Small-Molecule Organic Single-Crystal Transistor Array by Direct Ink-Jet Printing

Ink‐jet printed small‐molecule organic single‐crystal transistors are realized by using selective surface energy modification, precise control of volume density of ink droplets on spatially patterned areas, and a co‐solvent system to control solvent evaporation properties. The single‐crystal formati...

Description
Summary:Ink‐jet printed small‐molecule organic single‐crystal transistors are realized by using selective surface energy modification, precise control of volume density of ink droplets on spatially patterned areas, and a co‐solvent system to control solvent evaporation properties. The single‐crystal formation in bottom‐contact‐structured transistors via direct printing is expected to permit high‐density array fabrication in large‐area electronics.
