Structure of graphene and its disorders: a review

“…Further, the conductivity decreased rapidly with increasing thickness when the number of graphene layers ranged from 2 to 13, but decreased slowly and thereafter remained constant for layer numbers up to 165. These numerical simulation results were in agreement of the published experimental results [133,134]. More information about the properties of monolayer, bilayer and few-layer graphene can be found in Refs [119,135–139].…”

Enhanced performance of photonic crystal GaN light-emitting diodes with graphene transparent electrodes

“…From test results, shown in Figure 7(b), the slope of the I to V characteristics of graphene on the SiO 2 PC structure is 2.8 times as high as that on the planar substrate. The sheet resistance of graphene on the planar SiO 2 substrate is about 300 Ω/□ and the average sheet resistance of graphene on the PC structure is about 107 Ω/□, which is similar to other reports [15,22].…”

Temperature- and thickness-dependent electrical conductivity of few-layer graphene and graphene nanosheets

“…Thus, the average velocity of the electrons [Eqs. (5) and (6)] can be substituted for the average velocity of thermal motion. For the 2D electron gas, the average velocity of the thermal motion of electrons is presented in Eq.…”

“…Boland et al [30] demonstrated that the electrical conductivity of GNRs decreases with increasing thickness; a similar behavior is observed for graphite. Rouhi et al [5] found that the electrical resistivity of suspended FLG is approximately 3.35 μ /cm. Hwang and Das Sarma [31] theoretically calculated the temperature-dependent electrical conductivity of graphene using the Boltzmann transport equation and the mechanism of phonon scattering.…”

“…Single-layer graphene (SLG), few-layer graphene (FLG), graphene nanosheets (GNs), graphene nanoribbons (GNRs), and carbon nanotubes have attracted considerable interest because of their unique electrical, thermal, optical, and mechanical properties [1][2][3][4][5][6]. FLG and GNs are widely applied in nanoelectronics [7][8][9], supercapacitors [10][11][12], transparent conducting thin films [13][14][15], solar energy fuel cells [16][17][18], biochemical analysis and detection [19,20], and electromagnetic interference shielding and microwave absorption [21,22].…”
