Abstract

We studied the charge transport characteristics of the organic semiconductor 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-PEN) deposited by dip-coating of a solution in an azeotropic solvent mixture. Arrays of crystalline ribbons were obtained with a morphology controllable by variation of the coating speed U. The charge carrier mobility µ exhibited a systematic and reproducible dependence on the coating speed U and maximum values as high as µ ˜ 1.0 cm2/(V s).
