Abstract

original image

Strongly textured organic semiconductor micropatterns made of the small molecule dioctylbenzothienobenzothiophene (C8-BTBT) are fabricated by using a method based on capillary force lithography (CFL). This technique provides the C8-BTBT solution with nucleation sites for directional growth, and can be used as a scalable way to produce high quality crystalline arrays in desired regions of a substrate for OFET applications.
