ABSTRACT: In this
work, was obtained metallic decorated, single wall Carbon Nanotubes (SWCNTs)
using High Density Chemical Vapor Deposition (HDPCVD) system on chromium thin
films on a silicon wafers substrate. The characteristics of this deposition
method are capacity of the segregation of metallic nanoparticlesas seed for the
SWCNT growing. Use of magnetic particle decorated carbon nanotubes increases
the applications in magnetic devices, magnetic memory, and magnetic oriented
drug delivery. The CNTs’ spectra show a unique emission band, but due to the
presence of the chromium, the spectra obtained in this work showed many bands
that are related to the CNTs with different diameters. The CNTs obtained by the
HDPCVD system are highly aligned and showed metallic features. Results of this
work proved the possibility of obtaining the controlled deposition of aligned
single-walled CNTs forest films decorated with chromium and suggested future
studies in magnetic devices applications.
