Synthesis-condition dependence of carbon nanotube growth by alcohol catalytic chemical vapor deposition method

Synthesis-condition dependence of carbon nanotube growth by alcohol catalytic chemical vapor deposition method

We report the dependence of growth yield of single-walled carbon nanotubes (SWNTs) on heat-treatment time and catalyst film thickness by the alcohol catalytic chemical vapor deposition method. Three types of heat-treatment, synthesis of 30 min, synthesis of 30 min after annealing of 30 min, and synt...
