(a) Spin-orbital coupling constant (α R ) as a function of Vbg. (b) Rashba spin-splitting (\({{\rm{\Delta }}}_{R}\)) as a function of Vbg. (c) Comparison of \({{\rm{\Delta }}}_{R}\) and \({{\rm{\Delta }}}_{SO}\) as a function of Vbg and at Vtg = 0 V. (d) Dependence of \({{\rm{\Delta }}}_{R}\) and \({{\rm{\Delta }}}_{SO}\) on Vtg at a fixed back gate voltage of −35 V. Measurements were performed in vacuum at T= 4.2 K.
