Solution processed OTFTs with 1 cm/sup 2//V-s mobility

Abstract

This work presents fabricated solution processed organic thin film transistors (OTFTs) based on triethylsilylethynyl thienyl pentacene (TES thienyl pentacene) with 1 cm/sup 2//V-s field-effect mobility. The devices also have an on/off current ratio >10/sup 7/ and subthreshold slope near 1 V/decade. To our knowledge, these are the highest mobility solution processed OTFTs demonstrated to date and the first with performance comparable to thermally evaporated pentacene devices.
