The transverse spin-related currents at room temperature and different wavelengths corresponding to different longitudinal electric fields. The transverse spin-related currents at different wavelengths corresponding to longitudinal electric fields of a 0 V/cm, b + 4 V/cm, and c −4 V/cm as a function of light spot position. All lines in a are for ease of viewing, and lines in b and c are curves fitted in Eq. 1. d The AHE currents extracted by subtracting the ACPGE currents in a from the total spin-related photocurrents in b and c. The solid and dotted lines are curves of Gaussian fitting corresponding to AHE
