Experimental Observation of the Quantum Anomalous Hall Effect in a Magnetic Topological Insulator
Cui-Zu Chang, Jinsong Zhang, Xiao Feng +20
The quantized version of the anomalous Hall effect has been predicted to occur in magnetic topological insulators, but the experimental realization has been challenging. Here, we r…
Band engineering of Dirac surface states in topological insulators-based van der Waals heterostructures
Cui-Zu Chang, Peizhe Tang, Xiao Feng +5
The existence of gapless Dirac surface band of a three dimensional (3D) topological insulator (TI) is guaranteed by the non-trivial topological character of the bulk band, yet the…
Disentangling the magnetoelectric and thermoelectric transport in topological insulator thin films
Jinsong Zhang, Xiao Feng, Yong Xu +14
We report transport studies on (Bi,Sb)2Te3 topological insulator thin films with tunable electronic band structure. We find a doping and temperature regime in which the Hall coeffi…
Simultaneous electrical-field-effect modulation of both top and bottom Dirac surface states of epitaxial thin films of three-dimensional topological insulators
Cui-Zu Chang, Zuocheng Zhang, Kang Li +11
It is crucial for the studies of the transport properties and quantum effects related to Dirac surface states of three-dimensional topological insulators (3D TIs) to be able to sim…
Chemical potential dependent gap-opening at the Dirac surface states of Bi2Se3 induced by aggregated substitutional Cr atoms
Cui-Zu Chang, Peizhe Tang, Yi-Lin Wang +11
With angle-resolved photoemission spectroscopy, gap-opening is resolved at up to room temperature in the Dirac surface states of molecular beam epitaxy grown Cr-doped Bi2Se3 topolo…
Electrically tuned magnetic order and magnetoresistance in a topological insulator
Zuocheng Zhang, Xiao Feng, Minghua Guo +10
The Dirac-like surface states of the topological insulators (TIs) are protected by time reversal symmetry (TRS) and exhibit a host of novel properties. Introducing magnetism into T…
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…
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…
