Abstract
We report the development of hybrid complementary inverters based on p-channel organic and n-channel metal oxide thin-film transistors (TFTs) both processed from solution at < 200 degrees C. For the organic TFTs, a ternary blend consisting of the small-molecule 2,7-dioctyl[1] benzothieno[3,2-b][1]benzothiophene, the polymer indacenodithiophene-benzothiadiazole (C16IDT-BT) and the p-type dopant C60F48 was employed, whereas the isotype In2O3/ZnO heterojunction was used for the n-channel TFTs. When integrated on the same substrate, p- and n-channel devices exhibited balanced carrier mobilities up to 10 cm(2)/Vs. Hybrid complementary inverters based on these devices show high signal gain (> 30 V/V) and wide noise margins (70%). The moderate processing temperatures employed and the achieved level of device performance highlight the tremendous potential of the technology for application in the emerging sector of large-area microelectronics.
