Semiconductor-based spintronics systems have garnered particular interest because semiconductors can be integrated within modern-day electronics with the aim of improving the efficiency and storage capacity of devices.

Electrons in one spin state (say up) can propagate through the device, while spin-down electrons are reflected or scattered away.
