  • Electronic device
    Patent number: 9269774
    Abstract: An electronic device (1) includes a semiconductor substrate (3) having a front surface (7), a first electrode (8) and a second electrode (9) disposed on the front surface (7) of the substrate (3), wherein the first electrode (8) and the second electrode (9) each have at least one epitaxial graphene monolayer (10). The at least one epitaxial graphene monolayer (10) of the first electrode (8) forms an ohmic contact with the substrate (3) and the at least one epitaxial graphene monolayer (10) of the second electrode (9) forms a Schottky barrier with the substrate (3).
    Type: Grant
    Filed: June 18, 2012
    Date of Patent: February 23, 2016
    Assignee: Friedrich-Alexander-Universität Erlangen-Nürnberg
    Inventors: Heiko B. Weber, Michael Krieger, Stefan Hertel, Florian Krach, Johannes Jobst, Daniel Waldmann
  • Semiconductor component
    Patent number: 9263526
    Abstract: A semiconductor component (1, 20, 30) comprising a semiconductor substrate (3) composed of silicon carbide and comprising separate electrodes (4, 5) applied thereto, said electrodes each comprising at least one monolayer of epitaxial graphene (11) on silicon carbide, in such a way that a current channel is formed between the electrodes (4, 5) through the semiconductor substrate (3).
