Remarkable Mobility Increase and Threshold Voltage Reduction in Organic Field‐Effect Transistors by Overlaying Discontinuous Nano‐Patches of Charge‐Transfer Doping Layer on Top of Semiconducting Film

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 cm2 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.
