Wei-Ling SEAH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Organic field-effect-transistors with low contact resistance
    Patent number: 10276815
    Abstract: This invention provides a transistor device structure that incorporates a self-aligned doped contact formed by inserting a molecularly-thin layer of bonded anions between the semiconductor and the source-drain electrode array wherein the semiconductor is p-doped at the interface with the bonded-anion layer, and a method of making this structure using oxidant species incorporated into the molecularly-thin layer. The device shows ohmic hole injection and hole extraction at the contacts to give high-performance transistor characteristics with low contact resistance.
