The DOS in the quantum Hall regime consists of discrete energy levels broadened due to disorder. In this regime, the onset of electron injection into graphene takes place when μDot < −eVSrc and at the same time the dot is resonant with an unpopulated Landau level: −μGr +...
13.6.6 Landau Levels in Graphene Graphene reveals new physics in the integer quantum Hall effect. In graphene, the Landau levels are proportional to n (where n is the Landau level index), instead of the usual relation En=(n+1∕2)ℏωc for the Landau energies in semiconductors. Moreover...
The quantum Hall states of graphene have a filled Dirac sea of Landau levels. The short ranged SU(4) symmetry breaking interactions can induce a staggered polarization of the sea of Dirac-Landau levels. We study this effect in the extended Hubbard model on a honeycomb lattice using mean field...
The recently discovered flat electronic bands and strongly correlated and superconducting phases in magic-angle twisted bilayer graphene (MATBG)1,2 crucially depend on the interlayer twist angle, θ. Although control of the global θ with a precision of about 0.1 degrees has been demonstrated1,2,...
We study the discrete energy spectrum of curved graphene sheets in the presence of a magnetic field. The shifting of the Landau levels is determined for complex and realistic geometries of curved graphene sheets. The energy levels follow a similar square root dependence on the energy quantum number...
