Air stable complementary-like circuits, such as voltage inverters (see figure) and ring oscillators, are fabricated using ambipolar organic transistors based on a nickel dithiolene derivative. In addition to the complementary-like character of the circuits, the technology is very simple and fully compatible with the process flowchart for state-of-the-art unipolar organic circuits.
