Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy
Woojoo Lee, Qiang Gao, Yufei Zhao +20
Quantum spin Hall insulators, or synonymously known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of thi…
Interaction-driven flat band and charge order in Fe5GeTe2
Qiang Gao, Gabriele Berruto, Khanh Duy Nguyen +9
Flat electronic bands enable fascinating emergent phenomena such as superconductivity and charge orders. A prevailing approach to realizing flat bands is to engineer lattice geomet…
Spectroscopic evidence of intra-unit-cell charge redistribution in charge-neutral magnetic topological insulator Sb-doped MnBi6Te10
Khanh Duy Nguyen, Gabriele Berruto, Seng Huat Lee +5
The magnetic topological insulator MnBiTe has emerged as a promising candidate for realizing the quantum anomalous Hall effect (QAHE), owing to its ability to retain f…
A Topological Superconductor Tuned by Electronic Correlations
Haoran Lin, Christopher L. Jacobs, Chenhui Yan +15
A topological superconductor, characterized by either a chiral order parameter or a chiral topological surface state in proximity to bulk superconductivity, is foundational to topo…
