Spin hall conductivity
Web• The quantum spin Hall phase shares many similarities with the quantum Hall effect: - bulk excitation gap - gapless edge excitations - topological stability - 3D generalization • But there are also important differences: - Spin Hall conductivity not quantized (but non zero). - Edge states are not chiral, but “spin filtered”. WebDec 1, 2024 · These band structure properties are important for the spin Hall effect: as recently reported, multiple DNLs together with gap opening due to large SOC lead to large spin Hall conductivity [3, 4 ...
