Fractional quantum ferroelectric control of spin-valley locking and valley Hall effects in altermagnetic monolayer Cr2S2
Tao Yao, Quan Shen, Jiansheng Dong +1
The paper uses first‑principles calculations to show that a monolayer of Cr₂S₂ exhibits switchable fractional quantum ferroelectric states that control altermagnetic spin splitting…
Multistate ferroelectricity and switchable layer-locked anomalous valley Hall effects in bilayer ReIrGe2Se6
Tao Yao, Quan Shen, Jianing Tan +1
The paper predicts, via first‑principles calculations, that bilayer ReIrGe2Se6 exhibits four stable ferroelectric states whose switching controls layer‑locked anomalous valley Hall…
Interlayer sliding direction as a symmetry selector in altermagnetic bilayer Fe2WS4: Switchable anomalous Hall and anomalous valley Hall effects
Quan Shen, Jianing Tan, Tao Yao +2
The paper shows that sliding the layers of a 2D altermagnetic Fe2WS4 bilayer can reversibly switch its ferroelectric polarization, spin texture, and associated anomalous Hall and v…
Strain-tunable multipiezo effects in Janus monolayer Cr2SSe: Selective reversal of valley polarization and single-spin-channel anomalous valley Hall effect
Quan Shen, Jianing Tan, Tao Yao +2
Altermagnetism, the third class of collinear magnetic order, uniquely combines a zero net magnetization with spin polarized bands in reciprocal space, opening new avenues for two d…
Entropy Engineering-Regulated Electron-Phonon Coupling for Highly Efficient Photoluminescence in Se-doped WS2
Chi Zhang, Quan Shen, Mengmeng Zhang +8
The limited quantum yield of strained monolayer transition metal dichalcogenides grown by vapor-phase methods and during transfer-based stacking poses a fundamental challenge for t…
