Abstract
A three-terminal device includes first electrode, second electrode, gate electrode and an active channel coupling the first and second electrodes. The active channel has a layer of organic molecules with conjugated multiple bonds. The delocalized π-orbitals associated with the conjugated multiple bonds extend normal to the layer.
