Synthesis of Multilayer Graphene by Filtered Cathodic Vacuum Arc Technique

Abstract

Abstract-Filtered cathodic vacuum arc technique has been used to deposit amorphous carbon films of varying thickness on catalytic nickel thin film grown on SiO 2 /Si substrates. Subsequently these a-C films were annealed in vacuum at 650 ºC. Raman spectroscopy together with optical microscopy and scanning electron microscopy has revealed multilayer graphene formation.

Multilayered graphene films prepared at moderate temperatures using energetic physical vapour deposition

“…Despite it being widely used to produce carbon materials such as 'tetrahedral amorphous carbon' [26,27], 'diamond like carbon' [28] and a range of nanostructured graphitic materials [29], there is relatively little published on graphene synthesis [30][31][32]. These previous works on graphene only consider nickel substrates and employed a post deposition annealing process in order to obtain graphene.…”

Few Layer Graphene Derived from Wet Ball Milling of Expanded Graphite and Few Layer Graphene Based Polymer Composite

“…1 There are several methods of graphene synthesis apart from micromechanical cleavage, which are chemical vapor deposition (CVD) of hydrocarbons on metal substrates, 9 10 epitaxial growth on silicon carbide, [11][12][13] chemical functionalization combined with physical and chemical exfoliation, [14][15][16] liquid phase exfoliation of graphite, [17][18][19][20][21][22] arc discharge method, [23][24][25] unzipping of carbon nanotubes, 26 27 CVD substrate free synthesis, 28 29 electrochemical exfoliation, [30][31][32] solvothermal synthesis, 33 34 re-exfoilation of expanded graphite, 35 cathodic vacuum filtration arc technique etc. 36 But each process of synthesis has limitations to produce graphene in bulk quantity. The graphene produced by micromechanical cleavage by scotch tape that splits strongly layered material into individual atomic thick sheets.…”

“…Besides, the thickness of films can be controlled by adjusting the operating conditions [40,41]. Carbon paper (CP) is a type of carbon material that is fabricated with short carbon fibres that are arranged randomly.…”
