Three-dimensional porous graphene networks expand graphene-based electronic device applications
Yoshikazu Ito, Yoichi Tanabe, Katsuaki Sugawara +5
Graphene with excellent 2D characters has been required to expand their potentials for meeting applicational demands in recent years. As one avenue, several approaches for fablicat…
Band Structure Engineering of 2D Materials using Patterned Dielectric Superlattices
Carlos Forsythe, Xiaodong Zhou, Takashi Taniguchi +6
The ability to manipulate two-dimensional (2D) electrons with external electric fields provides a route to synthetic band engineering. By imposing artificially designed and spatial…
Lattice relaxation and energy band modulation in twisted bilayer graphenes
Nguyen N. T. Nam, Mikito Koshino
We theoretically study the lattice relaxation in the twisted bilayer graphene (TBG) and its effect on the electronic band structure. We develop an effective continuum theory to des…
Interaction-induced insulating states in multilayer graphenes
Mikito Koshino, Kyoka Sugisawa, Edward McCann
We explore the electronic ground states of Bernal-stacked multilayer graphenes using the Hartree-Fock mean-field approximation and the full-parameter band model. We find that the e…
Anomalous Hall effect in 2-phase transition-metal dichalcogenide monolayers on ferromagnetic substrates
Tetsuro Habe, Mikito Koshino
We study the anomalous Hall effect in monolayers of transition-metal dichalcogenides 2H- (=Mo, W, and =S, Se, Te) under a proximity effect of ferromagnetic substrate. I…
Magnetotransport in Weyl semimetal nanowires
Akira Igarashi, Mikito Koshino
We theoretically study the band structure and the electronic transport in the Weyl semimetal nanowires in magnetic fields, and demonstrate that the interplay of the Fermi-arc surfa…
