The Coexistence of van Hove Singularities and Superlattice Dirac Points in a Slightly Twisted Graphene Bilayer
Zhao-Dong Chu, Wen-Yu He, Lin He
We consider the electronic structure of a slightly twisted graphene bilayer and show the coexistence of van Hove singularities (VHSs) and superlattice Dirac points in a continuum a…
Evidence for Superlattice Dirac Points and Space-dependent Fermi Velocity in Corrugated Graphene Monolayer
Hui Yan, Zhao-Dong Chu, Wei Yan +10
Recent studies show that periodic potentials can generate superlattice Dirac points at energies in graphene (is the Fermi velocity of graphene and G is the reciprocal superlattice…
Controlling the Interlayer Coupling of Twisted Bilayer Graphene
Lan Meng, Wei Yan, Zhao-Dong Chu +5
The interlayer coupling of twisted bilayer graphene could markedly affect its electronic band structure. A current challenge required to overcome in experiment is how to precisely…
Flat Bands near Fermi Level of Topological Line Defects on Graphite
Lei Feng, Xianqing Lin, Lan Meng +3
Flat bands play an important role in the study of strongly correlated phenomena, such as ferromagnetism, superconductivity, and fractional quantum Hall effect. Here we report direc…
