1、Persistent Spin Current for a Rashba Spin-Orbit Coupling Quantum Wire;

2、Relativistic mean field theory of electron and first-,second-order Rashba effects

3、Relation between charge shot noise and spin polarization governed by Rashba spin orbit interaction

4、The energy structure in 2DEG in presence of the effect of Rashba spin-orbit coupling interaction has been studied in this thesis.

5、As for the 2deg with spin-orbit coupling, we firstly investigate the ballistic transport of electrons in the magnetic superlattice with both Rashba and Dresselhaus couplings.
