  • Light emitting diode having metal nanoparticle layered graphene
    Patent number: 8779411
    Abstract: The present disclosure provides a light emitting diode and a method of manufacturing the same. The light emitting diode includes a graphene layer on a second conductive semiconductor layer and a plurality of metal nanoparticles formed on some region of the graphene layer, whereby adhesion between the second conductive semiconductor layer comprised of an inorganic material and the graphene layer is enhanced, thereby securing stability and reliability of the light emitting diode. In addition, the light emitting diode allows uniform spreading of electric current, thereby allowing stable emission of light through a surface area of the light emitting diode.
    Type: Grant
    Filed: November 16, 2012
    Date of Patent: July 15, 2014
    Assignee: Gwanju Institute of Science and Technology
    Inventors: Dong Seon Lee, Jae Phil Shim, Seong Ju Park, Min Hyeok Choe, Do Hyung Kim, Tak Hee Lee
