Title:

SPIN POLARIZED CARRIER TRANSPORT DEVICE

Document Type and Number:

Japanese Patent JP2013026592

Kind Code:

A

Abstract:

To furthermore increase the transport distance of a spin polarized carrier in a semiconductor.

A spin polarized carrier transport device includes: a channel layer 101 comprising a semiconductor; a spin polarized carrier generation part 102; a surface acoustic wave generation part 103; and a spin orbit interaction adjustment part 104. The spin polarized carrier generation part 102 generates a spin polarized carrier at a carrier generation site of the channel layer 101. The surface acoustic wave generation part 103 generates a surface acoustic wave 131 passing the carrier generation site, on the channel layer 101. The spin orbit interaction adjustment part 104 makes same the magnitudes of different two spin orbit interactions acting on a conduction band electron in the channel layer 101.
