Abstract
In this paper, we report here that spin injection from an Fe Schottky contact produces a spin polarization of 32% in an AlGaAs/GaAs quantum well, demonstrate via the Rowell criteria that tunneling is the dominate transport process, and examine the atomic structure of the spin injecting interface with TEM.
