WebJul 5, 2024 · Furthermore, by considering spin–orbit coupling, spin and valley degeneracy splitting are achieved simultaneously in Hg-substituted MnPSe 3. A data storage device prototype is proposed for future applications based on the anomalous valley Hall effects in this ferrovalley material. WebAb initio calculations show that this thickness independent splitting pattern is a direct consequence of the giant spin-valley coupling which fully suppresses interlayer hopping at valence band edge near K points because of the sign change of the spin-valley coupling from layer to layer in the 2H stacking order. texliving https://boxh.net

WebAug 23, 2024 · Here, monolayer MoS2, when doped with vanadium at low (0.1 atomic %) concentrations, is shown to exhibit high spin-valley coupling, and hence a high degree of valley polarization at room-temperature. The atomic layers of MoS2 (MS) and V-doped MoS2 (VMS) are grown via the chemical vapor deposition-assisted method. WebHowever, no spin-valley couplings have been proposed for magnetic MXenes thus far. Herein, we demonstrate that surface engineering not only breaks the inversion symmetry of 2D MXenes but also induces valley polarizations with diverse magnetic orders, including ferromagnetism, ferrimagnetism and antiferromagnetism.
