Abstract
Various characteristics of the growth of carbon nanotubes (CNTs) were examined by using in-situ optical interference patterns. A de plasma chemical vapor deposition technique was used to grow the CNTs. Significant interference oscillations were seen during the growth of CNTs. The light absorption in CNTs exponentially decayed with increasing CNT length. From the optical interference curves, the growth rate and the termination length of the CNTs were precisely estimated. The optical interference curves provided considerable in-situ information, such as the length, the alignment, and the related growth properties of the CNTs.
