Abstract: In thiswork, was obtained metallic decorated, single wall Carbon Nanotubes (SWCNTs)using High Density Chemical Vapor Deposition (HDPCVD) system on chromium thinfilms on a silicon wafers substrate. The characteristics of this depositionmethod are capacity of the segregation of metallic nanoparticlesas seed for theSWCNT growing. Use of magnetic particle decorated carbon nanotubes increasesthe applications in magnetic devices, magnetic memory, and magnetic orienteddrug delivery. The CNTs’ spectra show a unique emission band, but due to thepresence of the chromium, the spectra obtained in this work showed many bandsthat are related to the CNTs with different diameters. The CNTs obtained by theHDPCVD system are highly aligned and showed metallic features. Results of thiswork proved the possibility of obtaining the controlled deposition of alignedsingle-walled CNTs forest films decorated with chromium and suggested futurestudies in magnetic devices applications.
