Intercalation‐Induced Phase Transitions in Ferroelectric α‐In2Se3

Advanced Science, EarlyView.
Using the electrolyte gating technique, the van der Waals ferroelectric semiconductor α‐In2Se3 undergoes a series of transitions from a ferroelectric semiconductor to a dirty metal and finally to a metal, accompanied by a structural transformation. Concurrently, the ferroelectric hysteresis window progressively narrows and eventually disappears with ...

Integer quantum Hall effect in bilayer Dice lattices

Physical Review Research
We investigate the quantum Hall effect in bilayer dice lattices with AA-BB-CC and AB-BC-CA stacking configurations, focusing on the interplay between flat band stability and band topology.

Ferromagnetic Interlayer Exchange Coupling in Magnetic Topological Insulator Sandwich Heterostructures

Advanced Science, EarlyView.
A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...

Quantum Hall effect and current distribution in the three-dimensional topological insulator HgTe

Physical Review Research
We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain.

Magnetic and Crystal Symmetry Control on Spin Hall Conductivity in Altermagnets

Advanced Science, EarlyView.
Crystal structures and schematic illustrations of the spin Hall effect (SHE) in altermagnets. High‐symmetry RuO2 exhibits conventional SHE, while tilted RuO2 shows trivial unconventional SHE (USHE) caused by structural tilting. CrSb and MnTe, with reduced magnetic symmetry, display intrinsic USHE arising from symmetry‐driven spin–momentum locking ...
