Flexible air-stable short-channel polymer organic field-effect transistor (OFET) arrays with high saturated output current density are demonstrated by utilizing a novel solution-processed naphthobisthiadiazole (NTz) based donor-acceptor semiconducting polymer (PNTz4T) and designing a three-dimensional vertical channel structure with an extremely large ratio of channel width to channel length. The saturated mean field-effect mobility of 0.16 cm 2/V s of the short-channel polymer devices remains over one month resulting in air-stable OFET arrays with high on/off ratio over 106 and powerful current-density exceeding 0.3 A/cm2 under low operation voltage, both of which meet the requirements for such applications as driving organic light-emitting diodes in active-matrix displays.
