  • Graphene-based MIM diode and associated methods
    Patent number: 9202945
    Abstract: An apparatus including first and second layers of electrically conductive material separated by a layer of electrically insulating material, wherein one or both layers of electrically conductive material include graphene, and wherein the apparatus is configured such that electrons are able to tunnel from the first layer of electrically conductive material through the layer of electrically insulating material to the second layer of electrically conductive material.
    Type: Grant

  • Photodetection
    Patent number: 8927964
    Abstract: Apparatus and methods are provided. A first apparatus includes: a semiconductor film; and at least one semiconductor nanostructure, including a heterojunction, configured to modulate the conductivity of the semiconductor film by causing photo-generated carriers to transfer into the semiconductor film from the at least one semiconductor nanostructure. A second apparatus includes: a semimetal film; and at least one semiconductor nanostructure, including a heterojunction, configured to generate carrier pairs in the semimetal film via resonant energy transfer, and configured to generate an external electric field for separating the generated carrier pairs in the semimetal film.
