Observation of high-temperature quantum anomalous Hall regime in intrinsic MnBiTe/BiTe superlattice
Haiming Deng, Zhiyi Chen, Agnieszka Wolos +11
The quantum anomalous Hall effect is a fundamental transport response of a topologically non-trivial system in zero magnetic field. Its physical origin relies on the intrinsically…

Spin memory of the topological material under strong disorder
Inna Korzhovska, Haiming Deng, Lukas Zhao +5
Robustness to disorder - the defining property of any topological state - has been mostly tested in low-disorder translationally-invariant materials systems where the protecting un…

Stable topological insulators achieved using high energy electron beams
Lukas Zhao, Marcin Konczykowski, Haiming Deng +9
Topological insulators are transformative quantum solids with immune-to-disorder metallic surface states having Dirac band structure. Ubiquitous charged bulk defects, however, pull…
