摘要：
In this paper, we report a new method to generate amorphous carbon. The growth of amorphous carbons was performed at atmospheric pressure using a high voltage pulsed power supply (20 kV and 25 kHz) under the methane flux. Pulsed discharges of methane gas at atmospheric pressure were generated using high voltage power supply. The pulsed discharge of methane gas was generated between two sharp wolfram electrodes. Three types of carbon was produced by this pulsed plasma namely powder carbon, soft and hard carbon. Carbon samples were investigated by Scanning Electron Microscopy, Energy Dispersive X-ray spectroscopy and X-ray diffraction. The carbon samples have amorphous structure according to XRD results without contamination according to EDX results.
