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

Solution‐Processable Organic Single Crystals with Bandlike Transport in Field‐Effect Transistors 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Materials Wiley

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.
