Three Important Nuclear Steps-Unsaturated, highly Supersaturated and Normal Supersaturated

　

The carbon concentration inside the catalyst particle vs. the carbon formation on

the catalyst particle surface during the nuclear process of the SWNT structure. (900 K)

 

A peak shows during the period between the time when the catalyst particle is just supersaturated and the time the carbon island formation lift off the catalyst particle, which means that the catalyst particle highly supersaturated in carbon is needed for the nucleation of small carbon formation on the catalyst particle surface.
