Solution‐Processable Organic Single Crystals with Bandlike Transport in Field‐Effect Transistors

Abstract

Simple solvent-vapor annealing was used to fabricate single crystals of dioctylbenzothienobenzothiophene on a polymer dielectric surface. By involving self-organized phase separation, crystal length is enhanced and a good semiconductor/insulator interface is obtained. The field-effect transistors (FETs) exhibit an average p-type FET mobility of 3.0 cm2 V−1 s−1, with a highest value of 9.1 cm2 V−1 s−1. The FET mobility increases as temperature decreases, which suggests intrinsic bandlike transport. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
