“…An effective-mass model using the Slonczewski-WeissMcClure (SWMcC) parameterisation [29] has been adopted, in which every parameter can be compared by relevant parameter in the tight-binding model. The band structure of the AB-stacked graphite can be studied by Slonczewski-Weiss (SW) model in the vicinity of six perpendicular edges of first Brillouin zone [30]. An analytic 4Â4 Hamiltonian matrix of the tight-binding method is so used to study the energy dispersions.…”

“…An analytic 4Â4 Hamiltonian matrix of the tight-binding method is so used to study the energy dispersions. The SW model only investigates the information of low energy band structures of graphite and due to the limitation of the model, the electronic properties are lacking at high energy [30]. In addition, SW model only investigates the energy dispersions through the HKH-axis, along which the electronic properties are isotropic.…”

“…In addition, SW model only investigates the energy dispersions through the HKH-axis, along which the electronic properties are isotropic. To study the magnetoband structures along the HKH-axis of graphite below the magnetic field parallel to the z-axis, the SW model is further extended by McClure [30]. To investigate the Landau level structure in detail, the effective-mass description of tight-binding couplings of bulk graphite in the SWMcC parameterisation can be used [21].…”

“…Electronic states are varied into Landau levels in the planes of graphite, which are coupled by the interlayer interactions through the HKHaxis. The existence of a finite peak of density of state (DOS) at Fermi energy and Landau levels can be predicted by this model [21,30]. The SWMcC as an effective mass model is no doubt a convenient method because it is very easy to diagonalise a 4Â4 matrix.…”

“…The SWMcC as an effective mass model is no doubt a convenient method because it is very easy to diagonalise a 4Â4 matrix. Therefore, a full band calculation is supposed, which can completely and specially describe the Bloch electrons subjected to magnetic field [30]. The energy dispersion of the TGN includes the sub-bands analogous to monolayer or bilayer and the Hamiltonian is actually decomposed into independent subsystems, which is efficiently equal to monolayer or bilayer [25].…”

In this study, one-dimensional vision of carrier movement based on the band structure of trilayer graphene nanoribbon in the presence of a perpendicular electric field is employed. An analytical model of ABA-stacked trilayer graphene nanoribbon carrier statistics as a fundamental parameter of field effect transistor (FET) in corporation with a numerical solution is presented in the degenerate and non-degenerate limits. The simulated results based on the presented model indicate that the model can be approximated by degenerate and non-degenerate approximations in some numbers of normalised Fermi energy. Analytical model specifies that carrier concentration in degenerate limit is strongly independent of normalised Fermi energy; however, in the non-degenerate limit, it is a strong function of normalised Fermi energy. The proposed model is then compared with other types of graphene. As a result, the developed model can assist in comprehending experiments involving trilayer graphene nanoribbon FET-based devices.
