Abstract

A thin-film triple metal catalyst was used for investigating the growth of multiwall and single-wall carbon nanotubes (SWCNT) by chemical-vapor deposition (CVD). A full map of the metals in the sample surface was constructed and their evolution followed at different deposition temperatures by using Nanoauger spectroscopy. The initial iron layer was transformed into nanosized particles at the surface during the formation of SWCNT at high temperatures. During the annealing process, the Al layer played an important role by being altered into Al xO y.
