Abstract

We have fabricated 2,7-dioctyl[1]benzothieno [3,2-b][1]benzothiophene (C8-BTBT)-based organic field-effect transistors (OFETs) with top-gate configurations having fluoropolymer gate insulators by spin-coating processes. Top-gate OFETs with spin-coated polycrystalline C8-BTBT films exhibit high maximum field-effect mobility of 4.1 cm2/Vs and low average threshold voltage of -7.0 V.
