抄録	The incorporation of a symmetric electrostatic potential into quantum wells (QWs) is proposed as a method for modifying the coefficient a of the Rashba spin-orbit interaction. In a symmetric QW for which a = a(so)E(z), where E-z is the perpendicular electric field, the constant a(so) can be controlled by the symmetric potential. The sign reversal of a(so) with the increasing strength of the symmetric potential is demonstrated in (001)-oriented GaAs/AlGaAs QWs via a tight-binding model. The present findings can be used to realize structures with vanishing a in nonzero E-z.
