Giant nonlinear hall effect in twisted wse2

WebDec 26, 2024 · By breaking inversion symmetry, a nonlinear Hall signal can be observed, even in the presence of time-reversal symmetry, quite different from the conventional Hall effects. Low-symmetry two-dimensional materials are promising candidates for the nonlinear Hall effect, but it is less known when a strong nonlinear Hall signal can be … WebThe nonlinear Hall effect describes a recently discovered phenomenon in which a time-reversal symmetric material with a Berry curvature dipole develops a transverse voltage …

WebJan 1, 2024 · We show the strain modulated transport properties of nonlinear Hall effect in monolayer WSe 2 with moderate hole-doping by gating. The second-harmonic Hall signals show quadratic dependence on electric field, and the corresponding orbital magnetization per current density M / J can reach as large as 60. WebIn this work, we show that a giant nonlinear Hall effect can exist in twisted bilayer WTe 2 system. The Berry curvature dipole of twisted bilayer WTe 2 (θ = 29.4°) can reach up to ~1400 Å, which is much larger than that in previously reported nonlinear Hall systems. janet yellen elected head of federal https://icechipsdiamonddust.com
