Interface Landau levels in graphene monolayer-bilayer junction
Mikito Koshino, Takeshi Nakanishi, Tsuneya Ando
Electronic structure of graphene monolayer-bilayer junction in a magnetic field is studied within an effective-mass approximation. The energy spectrum is characterized by interface…
Transmission through a boundary between monolayer and bilayer graphene
Takeshi Nakanishi, Mikito Koshino, Tsuneya Ando
The electron transmission between monolayer and bilayer graphene is theoretically studied for zigzag and armchair boundaries within an effective-mass scheme. Due to the presence of…
Anomalous orbital magnetism in Dirac-electron systems: Role of pseudo-spin paramagnetism
Mikito Koshino, Tsuneya Ando
The orbital diamagnetic susceptibility is calculated in monolayer and bilayer graphenes with band gap as well as in three-dimensional Dirac systems. It is demonstrated that the pse…
