  • Organic transistor inverter
    Patent number: 8053769
    Abstract: A transistor includes a first semiconductor layer associated with a first electrode; a second semiconductor layer associated with a second electrode; and a discontinuous layer between the first and second semiconductor layer. The discontinuous layer has a plurality of openings being formed on a non-uniform organic surface. Applications of the transistor include an inverter that operates at low supply voltage and high frequency.
    Type: Grant

  • Vertical organic transistor and method of fabricating the same
    Patent number: 7560728
    Abstract: A vertical organic transistor is disclosed, which includes at least: a collector contact layer disposed on a substrate; a first organic semiconductor layer disposed on the collector contact layer; a base contact layer disposed on the first organic semiconductor layer, wherein the base contact layer comprises no less than two layers of hetero-metal layers or hetero-conductive organic layers; a second organic semiconductor layer disposed on the base contact layer; and an emitter contact layer disposed on the second organic semiconductor layer. Device properties such as output current and Ion/Ioff rate can be improved by using the vertical organic transistor of this invention.
