摘要/Abstract

摘要： We have studied the characteristics of current induced nonequilibrium spin polarization in semiconductor-nanowire/s-wave superconductor junctions with strong spin-orbit coupling. It was found that within some parameter regions the magnitude of the current induced nonequilibrium spin polarization density in such structures will increase (or decrease) with the decrease (or increase) of the charge current density, in contrast to that found in normal spin-orbit coupled semiconductor structures. It was also found that the unusual characteristics of the current induced nonequilibrium spin polarization in such structures can be well explained by the effect of the Andreev reflection.
