Long-term Dynamics of the Electron-nuclear Spin System of a Semiconductor Quantum Dot
I. A. Merkulov, G. Alvarez, D. R. Yakovlev +1
A quasi-classical theoretical description of polarization and relaxation of nuclear spins in a quantum dot with one resident electron is developed for arbitrary mechanisms of elect…
Optical control of spin coherence in singly charged (In,Ga)As/GaAs quantum dots
A. Greilich, R. Oulton, E. A. Zhukov +9
Electron spin coherence has been generated optically in n-type modulation doped (In,Ga)As/GaAs quantum dots (QDs) which contain on average a single electron per dot. The coherence…
Multiple transfer of angular momentum quanta from a spin-polarized hole to magnetic ions in ZnMnSe/ZnBeSe quantum wells
A. V. Akimov, A. V. Scherbakov, D. R. Yakovlev +4
The magnetization kinetics in (Zn,Mn)Se/(Zn,Be)Se quantum wells has been studied on a ps-time scale after pulsed laser excitation. The magnetization induced by an external magnetic…
Optical pumping of electronic and nuclear spin in single charge-tunable quantum dots
A. S. Bracker, E. A. Stinaff, D. Gammon +8
We present a comprehensive examination of optical pumping of spins in individual GaAs quantum dots as we change the charge from positive to neutral to negative using a Schottky dio…
Optical Read-Out and Initialization of an Electron Spin in a Single Quantum Dot
A. Shabaev, Al. L. Efros, D. Gammon +1
We describe theoretically the resonant optical excitation of a trion with circularly polarized light and discuss how this trion permits the read-out of a single electron spin throu…
Manipulation of the Spin Memory of Electrons in n-GaAs
R. I. Dzhioev, V. L. Korenev, I. A. Merkulov +4
We report on the optical manipulation of the electron spin relaxation time in a GaAs based heterostructure. Experimental and theoretical study shows that the average electron spin…
