Solution shearing can deposit organic semiconductor thin films with large, aligned crystals from a range of materials. Top-contact transistors fabricated on solution-sheared thin films outperform equivalent devices fabricated through drop-casting. Our facile, versatile, and scalable technique requires small amounts of semiconductor material and can be used for large-area device fabrication, or as a rapid screening tool for high-mobility compounds.
