a The MR and Hall curves in the dark and under illumination with various wavelengths under the applied out-of-plane magnetic field at 5 K. b The magnetoconductance curves in the dark and at different wavelengths. The solid red curves are the best fits to the MF model. c The Rashba SOC effective field (Bso) and inelastic scattering field (Bi) extracted from (b) as a function of wavelength. d, e The derived carrier density (n1,2) and mobility (μ1,2) from the Hall effect as a function of wavelength according to the two-band model. The dashed lines indicate the Lifshitz transition point. The corresponding parameters of the dark condition are also included in (c–e).
