Abstract
Graphene is the new material that arises after carbon nanotubes (CNTs) era and has extraordinary optical, electronic and mechanical properties compared to CNTs. The 2D graphene is the sp(2) carbon allotropes compared to other dimensionality. It also can be in three forms that are zero-dimensional, one-dimensional or three-dimensional. The different dimensionality also called fullerenes, nanotubes and graphite. Therefore, the graphene is known as centre potential materials in expanding research area than others ever. The 2cm x 2cm silicon wafer was seeded with nickel (Ni) at different thickness by using sputter coater. The palm oil, carbon source, was placed in the precursor furnace and the silicon was placed in the second furnace (deposition furnace). The palm oil will mix with Nitrogen gas was used as carrier gas in the CVD under certain temperature and pressure to undergo pyrolysis proses. The deposition temperature was set at 1000 degrees C. The deposition time varied from 3 minutes, 5 minutes and 7 minutes. The graphene was growth at ambient pressure in the CVD system. Electron microscopy and Raman Spectrometer revealed the structural properties and surface morphology of the grapheme on the substrate. The D and G band appear approximately at 1350 cm(-1) and 1850 cm(-1). It can be concluded that the growth of graphene varies at different deposition time.
