Abstract
- We theoretically explore how to control electron-spin polarization in layered semiconductor nanostructure (LSN) by a [Formula: see text]-potential realized by atomic-layer doping. Due to Rashba spin-orbit coupling, a considerable spin polarization still remains even through a [Formula: see text]-potential is embedded in the LSN. Spin polarization ratio can be controlled by altering weight or position of [Formula: see text]-potential. Based on such an LSN, a structurally-tunable electron-spin filter may be obtained for spintronics device applications.
