Accessing the transport properties of graphene and its multi-layers at high carrier density
J. T. Ye, M. F. Craciun, M. Koshino +6
We present a comparative study of high carrier density transport in mono-, bi-, and trilayer graphene using electric-double-layer transistors to continuously tune the carrier densi…
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…
Spin-orbit coupling and broken spin degeneracy in multilayer graphene
Edward McCann, Mikito Koshino
Since the lattices of ABA-stacked graphene multilayers with an even number of layers, as well as that of monolayer graphene, satisfy spatial-inversion symmetry, their electronic ba…
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…
