Role of surface energy in the growth of carbon nanotubes via catalytic pyrolysis of hydrocarbons

We report an experimental study of carbon nanotube (CNT) growth via catalytic pyrolysis of acetylene. Surface free energy is shown to play a key role in determining the catalytic activity of the liquid droplet on the CNT tip and to be responsible for the constant nanotube diameter. A vapor-liquid-na...

Summary:We report an experimental study of carbon nanotube (CNT) growth via catalytic pyrolysis of acetylene. Surface free energy is shown to play a key role in determining the catalytic activity of the liquid droplet on the CNT tip and to be responsible for the constant nanotube diameter. A vapor-liquid-nanotube model is proposed for CNT growth.
