Abstract

Carbon Nanotubes (CNTs) were successfully synthesized on porous silicon (PSi) nanostructures using Thermal Chemical Vapor Deposition (TCVD) method. The PSi nanostructures were obtained using photo-chemical anodization method by varying the current density parameter of Porous Silicon. To synthesis the CNTs on PSi nanostructures, camphor oil is used as precursor and ferrocene as catalyst by keep the temperature constant at 800°C and deposition time at 15 minutes. The surface morphology of PSi and CNTs were studied using Field Emission Scanning Electron Microscope (FESEM) while Raman spectroscopy was carried out to study the degree of crystanillity of graphitization of CNTs. From AFM results, it can be showed that roughness at 0.120 nm is the optimum for the porous silicon nanostructures which is at 20 mA/cm2. While Raman Spectroscopy gives the ID/IG ratio. The lowest value of ID/IG ratio is 0.869 which is the optimum CNTs produced at 20 mA/cm of current density is represented by sample (c).
