Fig. 6: Diode efficiency phase diagram with both linear and higher order SOC.

The variation of the diode efficiency η is shown in the plane of cubic Rashba SOC parameters δ − γ choosing “optimal” values of the Zeeman fields (Bx/Δ0, Bz/Δ0) = (0.4, 0.0) in panel a and (Bx/Δ0, Bz/Δ0) = (0.4, 0.5) in panel b, respectively. We note a small enhancement in the maximum value of η for finite Bz. The other system parameters are chosen as: (By, α, μ/Δ0, β−1) = (0, 100 meV-nm, 0.5, 0.1 meV).
