Electric Properties of Dirac Fermions Captured into 3D Nanoporous Graphene Networks
Yoichi Tanabe, Yoshikazu Ito, Katsuaki Sugawara +12
Graphene, as a promising material of post-silicon electronics, opens a new paradigm for the novel electronic properties and device applications. On the other hand, the 2D feature o…
Modulation of mechanical resonance by chemical potential oscillation in graphene
Changyao Chen, Vikram V. Deshpande, Mikito Koshino +5
The classical picture of the force on a capacitor assumes a large density of electronic states, such that the electrochemical potential of charges added to the capacitor is given b…
Interaction-induced insulating state in thick multilayer graphene
Youngwoo Nam, Dong-Keun Ki, Mikito Koshino +2
Close to charge neutrality, the low-energy properties of high-quality suspended devices based on atomically thin graphene layers are determined by electron-electron interactions. B…
Cyclotron resonance of figure-of-eight orbits in a type-II Weyl semimetal
Mikito Koshino
We study the cyclotron resonance in the electron-hole joint Fermi surface of a type-II Weyl semimetal. In magnetic field, the electron and hole pockets touching at the Weyl node ar…
Charge inversion and topological phase transition at a twist angle induced van Hove singularity of bilayer graphene
Youngwook Kim, Patrick Herlinger, Pilkyung Moon +4
Van Hove singularities (VHS's) in the density of states play an outstanding and diverse role for the electronic and thermodynamic properties of crystalline solids. At the critical…
