Abstract

Abstract Short‐channel, high‐mobility organic transistors have been demonstrated using alkylated dinaphthothienothiophene. The field‐effect mobility for a transistor with a channel length of 2 mm was 1.46 cm2/Vs at operation of –15 V. The transconductance of the transistor reached to 500 µS/mm, which is one of the highest values in p‐channel organic transistors. The high mobility in short‐channel transistors is attributed to low contact resistance caused by Au/AuNi electrodes modified with pentafluorobenzenethiol. (© 2013 WILEY‐VCH Verlag GmbH & Co.
