Abstract
Organic semiconductor crystals (OSCs) present better charge transport characteristics than organic semiconductor films. OSCs have captured worldwide attention because they show great potential for optoelectronic devices, including organic field-effect transistors, active-matrix organic light-emitting diodes, radio frequency identification tags, and sensors. Well-patterned OSCs minimize crosstalk between neighboring devices and decrease leakage current. Therefore, patterning OSCs offers more opportunities for advanced optoelectronic applications. In this work, OSC patterning strategies, advances in applications based on well-patterned OSCs, and challenges and outlooks in the field are discussed.
