  • Publication number: 20150037515
    Abstract: A process for rapid synthesis of few-layer graphene films on Cu foil by microwave plasma chemical vapor deposition (MPCVD). The plasma/metal interaction can be useful for a rapid synthesis of such thin films. The process can produce films of controllable quality from amorphous to highly crystalline by adjusting plasma conditions during growth processes of ˜100 sec duration and with little or no supplemental substrate heating. Films have been characterized using Raman spectroscopy, scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The results help to identify the stages involved in the MPCVD deposition of thin carbon films on Cu foil. In yet other embodiments, the films are doped during synthesis by introduction of nitrogen gas in the reactor. Raman spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy and scanning tunneling microscopy reveal crystal structure and chemical characteristics.

  • Patent number: 8945690
    Abstract: A DLC film mass-producing apparatus 10 includes a chamber 12 connected to ground. In the chamber 12, a plurality of plate-shaped substrates 60 are disposed in parallel at regular intervals, without disposing a counter electrode that faces each of the plate-shaped substrates 60. Sputtering cleaning is then conducted by plasma discharge and an underlying contact layer is formed on each of the plate-shaped substrates 60. Subsequently, a DLC film is produced on each of the plate-shaped substrates 60 by injecting a carbon source gas into the chamber 12 such that the internal pressure of the chamber 12 reaches 0.1 to 10 Pa and applying a negative DC pulse voltage having a pulse half width of 0.1 to 3 ?sec to each of the plate-shaped substrates 60 to generate plasma.
