“…The methods for graphene production, excluding mechanical exfoliation [1], can be divided into two groups: chemical cleavage, including the step of graphite oxidation [5], [6]; and the methods for dosed position of carbon atoms on the substrate where under certain conditions graphene is formed [7]- [11].…”

“…High-quality graphene with a large area can be prepared on substrates of a catalytic transition metal -such as Ni or Cu -by thermal chemical vapour deposition (CVD) [7], [8]. Good quality graphene and direct control of the number of layers are achieved using the methods of the dosed deposition of amorphous carbon under the layer of Ni catalyst on Si/SiO 2 substrate [9], ion implantation of carbon clusters in the Ni catalyst layer [10], and pulsed laser carbon deposition [11]. Graphene can also be obtained using Ni powder as a catalyst in the thermal decomposition of SiC powder [12] and by pyrolysis of poly(methyl methacrylate) on particles of Ni powder [13].…”

“…Moreover, by providing energetic carbon species, PLD is an emerging technique to growth graphene at low temperature. 13,14 Au NPs were deposited on the fl-graphene to check the SERS activity. Rhodamine 6G, p-aminothiophenol (pATP), and a commercial pesticide were detected with a very good sensitivity.…”

“…The I 2D /I G ratio of MLG was ∼0.33 and increased with increasing substrate temperature. At substrate temperature of 700 • C, the I 2D /I G ratio of FLG became ∼0.47 which corresponds to less than 5 layers [33]. For monolayer graphene, the 2D band has single Lorentzian peak, whereas bilayer graphene has four Lorentzian subpeaks.…”

“…As substrate temperature increases, the mobility of the carbon adatoms increases due to increase in the diffusion coefficient, which is given by Eq. (1) [33].…”
