ABSTRACT:
Methods are disclosed for improving organic thin-film transistor (OTFT) performance by acid doping of the semiconducting layer. The semiconducting polymer comprising the semiconductor layer is doped with an acid, especially a Lewis acid, either during or after polymerization of the polymer, but prior to application of the polymer onto the OTFT. Also disclosed are OTFTs having enhanced charge carrier mobility produced by these methods.
