Anode Sheath Switching in a Carbon Nanotube Arc Plasma
Authors: A. Abe Fetterman, Yevgeny Raitses, and Michael Keidar
Abstract:
The anode ablation rate is investigated as a function of anode diameter for a carbon nanotube arc plasma. It is found that anomalously high ablation occurs for small anode diameters. This result is explained by the formation of a positive anode sheath. The increased ablation rate due to this positive anode sheath could imply greater production rate for carbon nanotubes.
