抄録

We recently determined the values of intrinsic spin-orbit (SO) parameters for In0.52Al0.48AS/In0.53Ga0.47As(10nm)/In0.52Al0.48As(InGaAs/InAlAs) quantum wells (QW), lattice-matched to (001) InP, from the weak localization/antilocalization analysis of the low-temperature magneto-conductivity measurements [1]. We have then studied the sub-band energy spectra for the InGaAs/InAlAs double QW system from beatings in the Shubnikov de Haas (SdH) oscillations. The basic properties obtained here for the double QW system provides useful information for realizing nonmagnetic spin-filter devices based on the spin-orbit interaction [2].
