Multi-Walled Carbon Nanotubes (MWCNTs) Synthesized on Ni-Cu NPs @ a-C: H Films: A Study of Cavity and Bearing Areas Percentage, ZX Topography, and the Width of the Surface Height Distribution with Different Ni Layers’ Thickness

Topological characterizations and optical density of the synthesized hydrogenated amorphous carbon Cu-Ni NPs @ a-C: H nanotubes (CNTs) with different surface morphology were studied in this report. Films deposited with Ni layer thickness of۵ nm have a maximum value of optical density especially in high energy range. Steps between ۱۸۰۰ to ۲۰۰۰KeV in the Rutherford backscattering (RBS) spectra are correspond to the presence of Cu and Ni elements. The thicknesses of films were measured by using SIMN-RA software. Films deposited with Ni layer thickness of ۱۵nm have a maximum value of the lateral size of nanotubes in about ۱۹.۷nm.The grown CNTs of films deposited with Ni layer thickness۱۵nm Ni, has a maximum value of diameter in about ۱۶.۲nm. The diagram of bearing area proportion height shows the percentage of cavities and single-layers. The cavity coverage of films was less than ۵% and the layer content of films was about ۹۰%.
