Abstract

Ferromagnetic contacts on a high-mobility two dimensional electron gas (2DEG) in a narrow gap semiconductor with strong spin-orbit interaction are used to investigate spin polarised electron transport. In ballistic samples, the predicted increase on the device resistance is observed when the: injector/detector magnetisation configuration is switched from parallel to anti-parallel. Spin dephasing and spin precession effects are studied as functions of temperature and 2DEG channel length. (C) 2001 Elsevier Science B.V. All rights reserved.
