Abstract
In this paper, we present the latest results concerning the characterization of the nanocarbon structures
obtained by TEM. The growths of amorphous carbons were performed at atmospheric pressure using a
high voltage pulsed power supply of 25 kV and 25 kHz, under the methane flux. The pulsed discharge
of methane gas was generated between two sharp wolfram electrodes. Two types of carbon were
produced by this pulsed plasma: soft carbon and hard carbon. Carbon samples were investigated also by
Scanning Electron Microscopy.
