Bias-controllable intrinsic spin polarization in a quantum dot
Qing-feng Sun, X. C. Xie
We propose a novel scheme to efficiently polarize and manipulate the electron spin in a quantum dot. This scheme is based on the spin-orbit interaction and it possesses following a…
The definition of the spin current: The angular spin current and its physical consequences
Qing-feng Sun, X. C. Xie
We find that in order to completely describe the spin transport, apart from spin current (or linear spin current), one has to introduce the angular spin current. The two spin curre…
Persistent spin current in spin-orbit coupling systems in the absence of an external magnetic field
Qing-feng Sun, X. C. Xie
The spin-orbit coupling systems with a zero magnetic field is studied under the equilibrium situation, {\it i.e.}, without a voltage bias. A persistent spin current is predicted to…
The angular spin current and its physical consequences
Qing-feng Sun, X. C. Xie
We find that in order to completely describe the spin transport, apart from spin current (or linear spin current), one has to introduce the angular spin current. The two spin curre…
Detection of Single Electron Charging in an Individual InAs Quantum Dot by Noncontact Atomic Force Microscopy
Romain Stomp, Yoichi Miyahara, Sacha Schaer +6
Single electron charging in an individual InAs quantum dot was observed by electrostatic force measurements with an atomic force microscope (AFM). The resonant frequency shift and…
