Current induced anisotropic magnetoresistance in topological insulator films
Jian Wang, Handong Li, Cui-Zu Chang +7
Topological insulators are insulating in the bulk but possess spin-momentum locked metallic surface states protected by time-reversal symmetry. The existence of these surface state…
Carrier-independent ferromagnetism and giant anomalous Hall effect in magnetic topological insulator
Cui-Zu Chang, Jin-Song Zhang, Min-Hao Liu +13
Breaking the time-reversal symmetry of a topological insulator (TI) by ferromagnetism can induce exotic magnetoelectric phenomena such as quantized anomalous Hall (QAH) effect. Exp…
Band structure engineering in (Bi1-xSbx)2Te3 ternary topological insulators
Jinsong Zhang, Cui-Zu Chang, Zuocheng Zhang +10
Three-dimensional (3D) topological insulators (TI) are novel quantum materials with insulating bulk and topologically protected metallic surfaces with Dirac-like band structure. Th…
Interplay between topological insulators and superconductors
Jian Wang, Cui-Zu Chang, Handong Li +8
Topological insulators are insulating in the bulk but possess metallic surface states protected by time-reversal symmetry. Here, we report a detailed electronic transport study in…
Crossover between weak localization and weak antilocalization in magnetically doped topological insulator
Minhao Liu Jinsong Zhang, Cui-Zu Chang, Zuocheng Zhang +10
Topological insulators (TI) are a new class of quantum materials with insulating bulk enclosed by topologically protected metallic boundaries. The surface states of three-dimension…
