The out-of-plane magnetoconductance (normalized by the quantum of conductance) at different V_G along (a) and (b) [001] directions. The dark grey dashed lines are the fitting lines by using Eq. (1). (c) The obtained fitting parameters B_SO (filled square) and B_ϕ (open circle) as a function of V_G along (black) and [001] (red) directions. (d) The τ_SO as a function of V_G along two directions, the inset shows the τ_i versus V_G. Comparing τ_SO with τ_i at different V_G along (e) and (f) [001] directions. Spin relaxation time vs. elastic scattering rate along two directions is shown in the insets of panels (e) and (f). The lines are a guide to the eye.
