Abstract
Probing surface order in nanotube systems is of fundamental importance for incorporation of these materials into practical electronic devices. The current study pertains to analysis of the surface orientation of vertically aligned single-walled and multi-walled carbon nanotubes arrays of varying length and composition. As expected, the p* intensity demonstrates an angular dependence. As the incidence angle is increased, there is a parallel rise in the p* intensity. However, in contrast to scanning electron microscopy (SEM) images, which depicted highly ordered arrays, polarization analysis indicated less localized surface order, which was partially attributed to the presence of caps and the bending of the tubes.Citation
