The complex nature of filling factor nu = 0 of monolayer graphene is studied in magnetotransport experiments. As a function of perpendicular magnetic field a metal-insulator transition is observed, which is attributed to disorder-induced Landau level broadening in the canted antiferromagnetic phase. ...
quantum Hall effect in the n=3 Landau level of monolayer graphene [Kim etal., Nat. Phys. 15, 154 (2019)], we consider a Bardeen-Cooper-Schrieffer variational state for composite fermions and find that the composite-fermion Fermi sea in this Landau level is unstable to an f-wave pairing....
The paper also presents a summary equations for ν calculation in the n = 0 and the n = 1 Landau level, but they can be eas- ily generalized for higher LLs. We have also pointed out the basic differences between the typical 2D semiconductor and the monolayer graphene, ...
This formulation has been employed successfully in electron transport for conventional sem- iconductor 2DEG18,20, and Within linear response more recently in graphene21 and theory, the Hall conductance is MoS222. ∑σ xy = gs e 2 (n h n=0,s=± + 1) [f (E n,s) − f (En+1,s...
proved that the presence of resonant scattering impurities near the Fermi level leads to an enhancement of the Seebeck coefficient and a higher figure of merit [32]. Here, we present a calculation of the temperature and magnetic field dependence of monolayer graphene thermoelectric properties. In ...

ductor due to the different degeneracy at N = 0 Landau level. Edge states in graphene have been the focus of much theoretical study because of the important role they play in transport. 11 It is well known that there are two basic types of edges in graphene, namely, the arm- chair ...
In charge neutral or slightly doped monolayer graphene, both the energy and the line width of the E2g phonon show clear variation with magnetic fields. This is attributed to magneto-phonon resonance between magnetoexcitations and the E2g phonons. In contrast, when the Fermi level of the ...
