a Schematics of the experimental setup for the voltage control spin Hall angle. b Typical angular-dependent RDH measured at the electric field from 0 kV/cm to −12 kV/cm, and then back to 0 kV/cm with the fitting results. c The obtained effective field HOOP under different electric fields with the linear fitting results versus the applied current. d The spin Hall angle of Bi2Se3 as a function of the external electric field. Error bars represent standard deviation. e The reversibility test of the electric field control process.
