Oscillating spin-orbit interaction as a source of spin-polarized wavepackets in two-terminal nanoscale devices.

Ballistic transport through nanoscale devices with time-dependent Rashba-type spin-orbit interaction (SOI) can lead to spin-polarized wavepackets that appear even for completely unpolarized input. The SOI that oscillates in a finite domain generates density and spin polarization fluctuations that leave the region as propagating waves. In particular, spin… CONTINUE READING
