This invention provides a method of making single-wall carbon nanotubes by
laser vaporizing a mixture of carbon and one or more Group VIII
transition metals. Single-wall carbon nanotubes preferentially form in
the vapor and the one or more Group VIII transition metals catalyzed
growth of the single-wall carbon nanotubes. In one embodiment of the
invention, one or more single-wall carbon nanotubes are fixed in a high
temperature zone so that the one or more Group VIII transition metals
catalyze further growth of the single-wall carbon nanotube that is
maintained in the high temperature zone. In another embodiment, two
separate laser pulses are utilized with the second pulse timed to be
absorbed by the vapor created by the first pulse.
