Vertically Grown Carbon Nanostructure Alignment: An Investigation by Using X-Ray Absorption Spectroscopy

This paper describes XRay Absorption Spectroscopy (XAS) on the carbon K edge of carbon nanostructures (nanotubes, nanofibers, and nanowalls). They are grown using a Plasma and Hot Filamentsenhanced Catalytic Chemical Vapor Deposition (PE HF CCVD) process on plain SiO2(8 nm thick)/Si(100) substrates. The XAS spectra are extremely sensitive to prior thermal treatment, as intense adsorption…
