First-principles study of electric-field-induced topological phase transition in one-bilayer Bi(111)
Hikaru Sawahata, Naoya Yamaguchi, Hiroki Kotaka +1
Using first-principles calculations, we found the topological phase transition induced by electric fields in one-bilayer Bi(111). The bandgap decreased with increasing electric fie…
First-principles study of spin texture and Fermi lines in Bi(111) multi-layer nanofilm
Hiroki Kotaka, Fumiyuki Ishii, Mineo Saito
We have performed a fully relativistic first-principles density functional calculation examining the surface state of bismuth (Bi) (111) multi-layer nanofilm, with up to 20 Bi bila…
Polarity tuning of spin-orbit-induced spin splitting in two-dimensional transition metal dichalcogenides semiconductors
Moh. Adhib Ulil Absor, Iman Santosa, Harsojo +4
The established spin splitting in monolayer (ML) of transition metal dichalcogenides (TMDs) that is caused by inversion symmetry breaking is dictated by mirror symmetry operations…
