Magneto-Induced Topological Phase Transition in Inverted InAs/GaSb Bilayers
Zhongdong Han, Tingxin Li, Long Zhang +1
We report a magneto-induced topological phase transition in inverted InAs/GaSb bilayers from a quantum spin Hall insulator to a normal insulator. We utilize a dual-gated Corbino de…
Emergence of ferromagnetism at the onset of moiré Kondo breakdown
Wenjin Zhao, Bowen Shen, Zui Tao +9
The interaction of a lattice of localized magnetic moments with a sea of conduction electrons in Kondo lattice models induces rich quantum phases of matter, such as Fermi liquids w…
Gate-tunable heavy fermions in a moiré Kondo lattice
Wenjin Zhao, Bowen Shen, Zui Tao +6
The Kondo lattice, describing a matrix of local magnetic moments coupled via spin-exchange interactions to itinerant conduction electrons, is a prototype of strongly correlated qua…
Anomalous Conductance Oscillations in the Hybridization Gap of InAs/GaSb Quantum Wells
Zhongdong Han, Tingxin Li, Long Zhang +2
We observe the magnetic oscillation of electric conductance in the two-dimensional InAs/GaSb quantum spin Hall insulator. Its insulating bulk origin is unambiguously demonstrated b…
Tuning Edge States in Strained-Layer InAs/GaInSb Quantum Spin Hall Insulators
Lingjie Du, Tingxin Li, Wenkai Lou +8
We report on a class of quantum spin Hall insulators (QSHIs) in strained-layer InAs/GaInSb quantum wells, in which the bulk gaps are enhanced by up to five folds as compared to the…
