Computational studies of catalytic particles for carbon nanotube growth

We review our computational studies of the melting temperatures and mechanisms of iron and iron-carbide clusters. Both isolated and supported clusters have been considered, and substrates with different shapes or pores have been simulated. It has been seen, for example, that the surface curvature-or local surface curvature-of the particle plays a dominant role in the melting mecha- nism and temperature. It has also been observed that the melting mechanism for small clusters is different to that of larger clusters. Copyright © 2009 American Scientific Publishers doi:10.1166/jctn.2009. 1001.
