WebDec 30, 2024 · We unveil the physical mechanism of selective directionality as the elastic spin controlled chiral coupling of valley phonon states, through both analytical theory and experimental measurement of the opposite local elastic spin density at different interface locations for different transport directions. The elastic spin of valley topological ... 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. fonlabs

WebDec 14, 2011 · The spin-valley coupling at the valence band edges suppresses spin and valley relaxation, as flip of each index alone is forbidden by the valley contrasting spin splitting. Valley Hall and spin Hall effects coexist in … Furthermore, we obtain the formula for energy splitting of valleys and adopt a tight-binding model for V Si 2 N 4, which elucidates the physical mechanism of spin-valley coupling. More interestingly, under 4% tensile strain, the intrinsic magnetic anisotropy of V Si 2 N 4 becomes out of plane, and spontaneous valley polarization is achieved. WebThis together with a large spin-orbit interaction and strong light-matter interactions makes TMDs especially suitable for investigating spin-valley physics.
