- We demonstrate threshold voltage controllable short-channel transistors and organic inverter circuits with top-contact electrodes on flexible substrates. The source and drain electrodes were thermally evaporated on semiconductor material and patterned using photolithography and a wet etching process. The mobility of the fabricated transistors with channel lengths (L CH) of 3 μm was 0.495 ± 0.037 cm2 V？1 s？1, which is 91% of that of a long-channel transistor with L CH of 50 μm. Finally, switching voltage (V SW) controllable organic inverter circuits are demonstrated with a wide-range tunability of over 1.91 V at a supply voltage (V DD) of 3 V and a gain over 75.8 (V/V).
