Resonant Transmission through Double Quantum Dots: Model and Numerical Results
Yuhui He, Qin-Wei Shi
Via projection operator technology, we restrict our discussion of Double Quantum Dots system in subspaces of fixed electron population. When an incident electron tries to pass thro…
Spin filtering through a double-bend structure
Q. W. Shi, J. Zhou, M. W. Wu
We propose a simple scheme for the spin filter by studying the coherent transport of electrons through a double-bend structure in a quantum wire with a weak lateral magnetic potent…
Spin-dependent quantum transport in periodic magnetic modulations: Aharonov-Bohm ring structure as a spin filter
M. W. Wu, J. Zhou, Q. W. Shi
Quantum interference in Aharonov-Bohm (AB) ring structure provides additional control of spin at mesoscopic scale. We propose a scheme for spin filter by studying the coherent tran…
Spin-dependent transport in lateral periodic magnetic modulations: a novel scheme for spin filters
J. Zhou, Q. W. Shi, M. W. Wu
A novel scheme for spin filters is proposed by studying the coherent transport of electrons through the quantum wires with lateral magnetic modulations. Unlike other schemes in the…
Spin oscillations in transient diffusion of a spin pulse in n-type semiconductor quantum wells
M. Q. Weng, M. W. Wu, Q. W. Shi
By studying the time and spatial evolution of a pulse of the spin polarization in -type semiconductor quantum wells, we highlight the importance of the off-diagonal spin coheren…
