Spin-photovoltaic effect in quantum wires due to inter-subband transitions
A. Fedorov, Yu. V. Pershin, C. Piermarocchi
We consider the current induced in a quantum wire by external electromagnetic radiation. The photocurrent is caused by the interplay of spin-orbit interaction (Rashba and Dresselha…
Persistent and radiation-induced currents in distorted quantum rings
Yuriy V. Pershin, Carlo Piermarocchi
Persistent and radiation-induced currents in distorted narrow quantum rings are theoretically investigated. We show that ring distorsions can be described using a geometrical poten…
Time-Resolved Spectroscopy of Single Excitons Bound to Pairs of Te Isoelectronic Impurity Centers in ZnSe
A. Muller, P. Bianucci, C. Piermarocchi +4
Tellurium impurity centers in ZnSe were individually probed with time-resolved photoluminescence (PL) spectroscopy. Resolution-limited peaks with an ultra-low spatial density origi…
Spin Photovoltaic Effect in Quantum Wires with Rashba Interaction
Yuriy V. Pershin, Carlo Piermarocchi
We propose a mechanism for spin polarized photocurrent generation in quantum wires. The effect is due to the combined effect of Rashba spin-orbit interaction, external magnetic fie…
Laser-controlled local magnetic field with semiconductor quantum rings
Yuriy V Pershin, Carlo Piermarocchi
We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed t…
Coherent control of lattice deformations in quantum wires by optical self-trapping
M. V. Katkov, C. Piermarocchi
We investigate theoretically a semiconductor quantum wire under the effect of an intense off-resonant cw laser. We show that in the regime of strong exciton-phonon coupling the lig…
