  • Patent number: 10755939
    Abstract: Disclosed is a method of manufacturing multilayer graphene, including (a) contacting of a metal substrate with a nonmetal element, (b) reduction through heat treatment, and (c) chemical vapor deposition of a graphene precursor on the metal substrate containing the nonmetal element dissolved therein, thereby manufacturing multilayer graphene that is doped with the nonmetal element on the metal substrate. In the multilayer graphene thus manufactured, the number of graphene layers and the work function are simultaneously adjusted by controlling the concentration of doped nonmetal element in a thickness direction of graphene through interactions related to the reduction of the nonmetal element dissolved in a copper catalyst and the growth of graphene, and moreover, the stacking structure of graphene is maintained and the optoelectronic properties of multilayer graphene can be controlled by simultaneously regulating graphene growth and doping during the synthesis procedure without additional processing.

  • Patent number: 10739811
    Abstract: The present invention relates to a design technology of a phase locked loop (PLL) for generating an accurate clock frequency in a clock synchronization system. The present invention suggests a new structure based on a hardware description language (HDL), and thus reduces a chip area of a frequency synthesizer while obtaining a wide frequency operation range. Furthermore, since only the HDL is used, the entire frequency synthesizer becomes all-synthesizable, and auto layout (auto P&R) can be achieved through a tool, which makes it possible to reduce a design cost of a designer.
