Semiconductor Spintronics
ABSTRACT
In semiconductor spintronics, electron spin rather than charge is the key property. This paper describes several
spin-related devices using spin-orbit interaction. We have experimentally confirmed that the spin-orbit interaction in a
semiconductor two-dimensional electron gas channel can be controlled by a gate voltage. This is the first step towards the
creation of functional spin devices. The operating principles of a spin field effect transistor, a spin filter, and a spin interference
device are discussed.
