摘要:
It is shown, using combined structural and chemical analysis modes of transmission electron microscopy, that various filled nanotubes can be produced by arcing a graphite cathode and a graphite anode doped with the filling element and a small quantity of sulfur. A growth mechanism based on a catalytic process involving carbon, a metal and sulfur is proposed.
