Previous studies using an a-iron catalyst showed that the rate of carbon filament growth was linearly proportional to the gas-phase carbon activity (ac) at lower u,. At higher a, the rate then became nearly independent of the gas-phase carbon activity. It was also reported that y-iron did not show t
## Abstract Organized carbon nanotubes (CNTs) have been grown at a fast rate by a gasβphase, catalytic CVD technique at 600β750βΒ°C for 15βmin with the iron pentacarbonyl/acetylene/hydrogen system. The CNT growth at various temperatures and flow rates of iron pentacarbonyl, acetylene, and hydrogen,
