Top-view of a Thin-film Transistor

Image courtesy Loo Research GroupThis is a top-view of a thin-film transistor, the basic building block for integrated circuits. The source and drain interdigitated electrodes of this transistor consist of a conductive polymer, polyaniline, that is directly patternable from an aqueous dispersion. Its active component (green rectangle) is pentacene, an organic semiconductor.
