Abstract
The values of the Rashba spin-orbit coupling constant α for MOCVD-grown In0.52Al0.48As/In0.53Ga0.47As/- In0.52Al0.48As quantum wells were studied using weak antilocalization analysis as a function of the structural inversion asymmetry (SIA) of the quantum well (QW). A clear transition from positive to negative magnetoresistance near B=0 T was observed by changing the SIA of the QWs. Furthermore, a quantitative agreement was found between theoretical and experimental values of α as a function of both the SIA and/or the sheet carrier density of the QWs.
