摘要：

An effective strategy for significantly increasing the organic transistor mobility with simultaneous reduction of the threshold voltage utilizing discontinuous nano-patches of charge-transfer doping layer is demonstrated. By overlaying the nano-patches on top of a given semiconducting film, mobility and threshold voltage of p-type pentacene are remarkably improved to 4.52 cm 2 V-1s-1 and -0.4 V, and those of n-type Hex-4-TFPTA are also improved to 2.57 cm2 V-1s -1 and 4.1 V. © 2013 WILEY-VCH Verlag GmbH & Co.
