Abstract

We examined single crystal growth of benzothienobenzothiophene-based organic semiconductors by solution coating method using liquid crystal and investigated its electrical characteristics. As the results, we revealed that the averaged mobility in the saturation region reached 2.08 cm²/Vs along crystalline b-axis, and 1.08 cm²/Vs along crystalline a-axis.
