Visualization of Strain-Induced Landau Levels in a Graphene - Black Phosphorus Heterostructure
Thi-Hai-Yen Vu, Pin Lyu, Na Hyun Jo +8
Strain-induced pseudo magnetic fields offer the possibility of realizing zero magnetic field Quantum Hall effect in graphene, possibly up to room temperature, representing a promis…
Large bandgap quantum anomalous hall insulator in a designer ferromagnet-topological insulator-ferromagnet heterostructure
Qile Li, Chi Xuan Trang, Weikang Wu +5
Combining magnetism and nontrivial band topology gives rise to quantum anomalous Hall (QAH) insulators and exotic quantum phases such as the QAH effect where current flows without…
Nano-mosaic of Topological Dirac States on the Surface of Pb5Bi24Se41 Observed by Nano-ARPES
Kosuke Nakayama, Seigo Souma, Chi Xuan Trang +9
We have performed scanning angle-resolved photoemission spectroscopy with a nanometer-sized beam spot (nano-ARPES) on the cleaved surface of Pb5Bi24Se41, which is a member of the (…
Metal-insulator transition and tunable Dirac-cone surface state in the topological insulator TlBi1-xSbxTe2 studied by angle-resolved photoemission
Chi Xuan Trang, Zhiwei Wang, Keiko Yamada +5
We report a systematic angle-resolved photoemission spectroscopy on topological insulator (TI) TlBi1-xSbxTe2 which is bulk insulating at 0.5 < x < 0.9 and undergoes a metal-insulat…
Unexpected Dirac-Node Arc in the Topological Line-Node Semimetal HfSiS
D. Takane, Z. Wang, S. Souma +5
We have performed angle-resolved photoemission spectroscopy on HfSiS, which has been predicted to be a topological line-node semimetal with square Si lattice. We found a quasi-two-…
