Spin and Valley Polarized Multiple Fermi Surfaces of α-RuCl/Bilayer Graphene Heterostructure
Soyun Kim, Jeonghoon Hong, Kenji Watanabe +4
We report the transport properties of -RuCl/bilayer graphene heterostructures, where carrier doping is induced by a work function difference, resulting in distinct electron…
New class of 3D topological insulator in double perovskite
Shu-Ting Pi, Hui Wang, Jeongwoo Kim +3
We predict a new class of three-dimensional topological insulators (TIs) in which the spin-orbit coupling (SOC) can more effectively generate a large band gap at point. The ban…
Tunable spin-orbit coupling and symmetry-protected edge states in graphene/WS
Bowen Yang, Min-Feng Tu, Jeongwoo Kim +6
We demonstrate clear weak anti-localization (WAL) effect arising from induced Rashba spin-orbit coupling (SOC) in WS-covered single-layer and bilayer graphene devices. Contrary…
Topological phase transition in Dirac fermionic heterostructures
Jeongwoo Kim, Jinwoong Kim, Ki-Seok Kim +1
Materials with non-trivial topology in their electronic structures enforce the existence of helical Dirac fermionic surface states. We discovered emergent topological phases in the…
Topological insulating behaviour in conducting property of crystalline Ge-Sb-Te
Jeongwoo Kim, Jinwoong Kim, Seung-Hoon Jhi
We report a discovery, through first-principles calculations, that crystalline Ge-Sb-Te (GST) phase-change materials exhibit the topological insulating property. Our calculations s…
