Abstract

We demonstrate the influence of angular mismatch on the field-effect mobility in solution-processed organic thin-film transistors based on the study of anisotropic organic semiconductor (OSC) layer characteristics. The mobility alteration caused by angular mismatch was significantly affected by the molecular alignment and crystallinity characteristics. In particular, the sensitivity of mobility increased with angular mismatch. This tendency was more pronounced as the molecular alignment and crystallinity were enhanced. These results clearly show the dependence of the anisotropic mobility properties, which were induced by angular mismatch, on the OSC film characteristics.
