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. This vertical flowing method provide us with phase-separated film (TIPS pentcene (up)/ i-PMMA(down) after drying. As fabricated on a highly capacitive 20 nm-thick Al 2O 3 dielectric, our device displayed a high mobility of 0.20cm 2/Vs, a low operation voltage of -10 V, and little hysteresis.
