Abstract
A study was performed on the in situ growth rate measurements and length control during chemical vapor deposition of vertically aligned arrays of multiwall carbon nanotubes (VAA-MWNT). The attenuation of a reflected HeNe laser beam and Fabry-Ṕerot interference fringes were used to measure the length of VAA-MWNT throughout the first 3-8 μm of growth. It was found that the growth rates for VAA-MWNT varied depending on the catalyst preparation, temperature and time.
