Details
- Creates CNTs through arc-vaporization of two carbon rods placed end to end, separated by few mm, in an enclosure that is usually filled with inert gas (Helium) at low pressure. A direct current of order of few hundreds Ampere (based on Graphite Current Density), driven by a potential difference of approximately 20 - 50 V, creates a high temperature discharge between the two electrodes. The discharge vaporizes the surface of one of the carbon electrodes, and forms a small rod-shaped deposit on the other electrode. High yield of CNTs depends on the uniformity of the plasma arc, and the temperature of the deposit forming on the carbon electrode.
