  • Incorporation of functionalizing molecules in nano-patterned epitaxial graphene electronics
    Patent number: 8221884
    Abstract: In a method of making graphite devices, a thin-film graphitic layer disposed against a preselected face of a substrate is created on the preselected face of the substrate. A preselected pattern is generated on the thin-film graphitic layer. At least one functionalizing molecule is attached to a portion of the graphitic layer. The molecule is capable of interacting with ? bands in the graphitic layer.
    Type: Grant
    Filed: June 24, 2011
    Date of Patent: July 17, 2012
    Assignee: Georgia Tech Research Corporation

  • Patterned thin film graphite devices and method for making same
    Patent number: 7327000
    Abstract: In a method of making graphite devices, a preselected crystal face of a crystal is annealed to create a thin-film graphitic layer disposed against selected face. A preselected pattern is generated on the thin-film graphitic layer. A functional structure includes a crystalline substrate having a preselected crystal face. A thin-film graphitic layer is disposed on the preselected crystal face. The thin-film graphitic layer is patterned so as to define at least one functional structure.
