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…
Precision extraction of the deuteron electric polarizability via the Baldin sum rule with full low-energy coverage
Zi-Rui Hao, Gong-Tao Fan, Qian-Kun Sun +21
The photodisintegration cross sections of the deuteron have been systematically measured over the photon energy range of 2.33-19.65 MeV at the Shanghai Laser Electron Gamma Source…
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…
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…
Realizing Intrinsically Glass-like Thermal Transport via Weakening the Ag-Ag Bonds in Ag Octahedra
Xingchen Shen, Zhonghao Xia, Jun Zhou +4
Crystals exhibiting glass-like and low lattice thermal conductivity () are not only scientifically intriguing but also practically valuable in various applications, inc…
