Paper Title
Effect of Weight Percentage to Grow CNTS on PSI/ZNO Nanostructures by Thermal-CVD

Abstract
In this work, multi-walled carbon nano tubes (MWCNs) were synthesized using double-furnace thermal chemical vapor deposition technique at 750oC on different substrates. Palm oil was used as a carbon natural source, ferrocene as a catalyst and nitrogen gas as a carrier gas. The precursor were vaporized at 475oC carried by nitrogen gas which flow at constant rate 150 sccm/min. Carbon nano tubes characterized by using field emission scanning electron microscopy and Raman spectroscopy to check its structure and crystallites. Carbon nano tubes with uniform diameter were found grown on porous silicon with good crystal structures compare to other substrates. Based on micro-Raman spectroscopy result, the peak of carbon nano tubes (around 1 300 to 1 600 nm) was detected. Keywords - Porous Silicon; ZnO Nanostructures; Carbon Nanotubes; Raman Spectroscopy
