Topological Interstitial-Electron Conductor
Tingli He, Xiaoming Zhang, Chaoxi Cui +5
Electron transport in solids arises primarily from two mechanisms: freely moving bulk electrons in metals, and gapless boundary states in topological insulators. Here, we report a…
Type-II Antiferroelectricity
Yang Wang, Zhi-Ming Yu, Chaoxi Cui +6
Antiferroelectricity (AFE) is a fundamental concept in physics and materials science. Conventional AFEs have the picture of alternating local electric dipoles defined in real space…
Kagome on beta-Sb with valley-hot Berry curvature and tunable intrinsic SHC
Yang Wang
Large-area, single-crystalline antimonene polygonal domains self-assemble on Al(111) at room temperature without forming an interfacial alloy layer by MBE. Beyond the beta-Sb phase…
Quantized Spin-Hall Conductivity in Altermagnet FeTeO with Mirror-Spin Coupling
Run-Wu Zhang, Chaoxi Cui, Yang Wang +3
Due to spin-orbit coupling (SOC), crucial for the quantum spin Hall (QSH) effect, a quantized spin-Hall conductivity has not yet been reported in QSH insulators and other realistic…
Unconventional topological Weyl-dipole phonon
Jianhua Wang, Yang Wang, Feng Zhou +5
A pair of Weyl points (WPs) with opposite Chern numbers can exhibit an additional higher-order topological charge, giving rise to the formation of a Weyl di…
