Polarization Rotation Drives a Spin-Topological Transition in Ferroelectric Bismuth Monolayer
Jinming Zhai, Lingzhi Cao, Yateng Wang +4
Bismuth monolayer is the first two-dimensional elemental ferroelectric and an appealing platform for coupling polar order to spin-orbit-driven topology. However, its microscopic sw…
Weak Polar Optical Phonon Scattering Decouples Electron and Phonon Transport in Layered Thermoelectric Materials
Zhonghao Xia, Michele Reticcioli, Yateng Wang +3
High-performance thermoelectric (TE) materials are crucial for efficient waste-heat recovery and solid-state cooling technologies. A persistent challenge in TE materials design ari…
Hidden Chiral Ferroelectricity in AgNbO Perovskite
Ying Song, Lingzhi Cao, Jinming Zhai +4
AgNbO is a lead-free perovskite with considerable potential for energy storage and optoelectronic applications, yet its low-temperature crystal structure has remained controver…
Strong Intra- and Interchain Orbital Coupling Leads to Multiband and High Thermoelectric Performance in NaAu ( = P, As, Sb, and Bi)
Zhonghao Xia, Zhilong Yang, Yali Yang +2
The intrinsic coupling among electrical conductivity (), Seebeck coefficient (), and lattice thermal conductivity () imposes a fundamental limit on the dime…
Stacking effects on magnetic, vibrational, and optical properties of CrSBr bilayers
Huicong Li, Yali Yang, Zhonghao Xia +4
The van der Waals layered semiconductor CrSBr, which exhibits A-type antiferromagnetism and a relatively high Néel temperature, has been successfully exfoliated into atomically th…
