摘要：
We discuss device concepts for creating spin-polarized current sources without external magnetic fields, using non-magnetic 6.1 Angstrom semiconductor resonant tunneling structures. Spin filters, spin pumps, and spin transistors that exploit structural and bulk inversion asymmetries will be examined. (C) 2003 Elsevier B.V. All rights reserved.
