Large Scale Graphene by Chemical Vapor Deposition: Synthesis, Characterization and Applications 171 Si/SiO2 wafers can be very useful for device fabrication, and our approach may serve as the foundation for the growth of single-domain graphene over macro-scale areas such as complete wafers. Fig. 10. Micro Raman maps of IG’/IG of about 800 spectra collected over 3000 μm2 area on as- grown graphene atop Ni (111) (a) and polycrystalline Ni (d) surfaces. Micrographs of the areas analyzed on Ni (111) (b) and polycrystalline Ni (e). Optical image of graphene grown on Ni (111) (c) and polycrystalline Ni (f) after transferred onto Si.SiO2 substrates. 3. Applications of large scale graphene Graphene outstanding electrical and thermal conductivities make it an exciting material with high potential to replace silicon and surpass its performance in the next generation of semiconductors devices. Applications of graphene films are strongly linked to its electronic structure. The energy dispersion of graphene is given by: , 1 4 √ cos 4 / (1) The positive part of the energy dispersion describes the * anti-bonding energy band and the negative part is the bonding energy band. Interestingly, the * anti-bonding and bonding bands are degenerate at the Κ points through which the Fermi energy passes. The first significant feature of this result is that, since the energy band is exactly symmetric about the point E = E2p = 0, and this condition is met only at Dirac point. It follows that for exactly half filling of the band the density of states at the Fermi level is exactly zero and undoped graphene is a perfect semimetal. At zero doping, the lower half of the band is filled exactly up to the Dirac Point. If by applying a suitable “gate” voltage to the graphenePDF Image | GRAPHENE SYNTHESIS CHARACTERIZATION PROPERTIES
