  • 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.
