Fig. 4
Temperature dependence of the PISHE current, spin transverse force, and electron diffusion length of the GaAs/AlGaAs 2DEG. a Experimental and modeling results of the PISHE current as a function of the light spot locations measured at different temperatures. The solid squares are the experimental data, and the solid lines are the fitting results. b, c Spin transverse force and electron diffusion length as a function of temperature, respectively. The dashed line in b is the guide for the eyes, and the solid line in c is obtained from [42]
