Spin injection and accumulation in inhomogeneous semiconductors

We present a study of spin transport in charge and spin inhomogeneous semiconductor systems. In particular, we investigate the propagation of spin-polarized electrons through a boundary between two semiconductor regions with different doping concentrations. We use a theoretical and numerical method, presented in this paper, based on a self-consistent treatment of a two-component version of the ...

Enhancement of Electron Spin Polarization in Semiconductors

An extension of the original Overhauser effect to a more general nonequi-librium state was proposed by G. Feher, and demonstrated by Clark and Feher some forty years ago. It is suggested here that it might be possible to produce excess electron spin polarization by allowing the role of the nuclei to be played by other magnetic entities, such as paramagnetic impurities or adjacent magnetically o...
