dc.description.abstractSpin-orbit interaction parameter (alpha) can be obtained by measuring the Shubnikov-de Haas oscillation, but this method is valid at only very low temperature. The current induced spin polarization in a 2-D electron gas layer is measured by potentiometric geometry which measures spin dependent chemical potential shifts. Subsequently, a spin-orbit interaction parameter can be extracted up to T = 250 K. In an inverted In0.52Al0.48As/In0.53Ga0.47As/In0.52Al0.48As quantum well system, alpha of 5.65 x 10(-12) eVm and 3.85 x 10(-12) eVm are obtained at T = 1.8 and 250 K, respectively.-
