Abstract

We report on the solution-processed thin-film transistors (TFTs) fabricated by the vertical flowing of the viscous 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene) and isotatic (i-) poly-(methyl methacrylate) (PMMA) blend. According to the optical-absorption and X-ray diffraction spectra, the solution-processed film appeared self-assembled with TIPS-pentacene (up) and i-PMMA dielectric (down) layers on substrates. As fabricated on a highly capacitive 100 nm-thick AlOx dielectric, our device displayed a high mobility of 0.34 cm2/V s, a low operation voltage of -15 V, and little hysteresis.
