Dynamics and control of nonradiative excitons - free carriers mixture in GaAs/AlGaAs quantum wells
A. S. Kurdyubov, A. V. Trifonov, B. F. Gribakin +9
Dynamics of nonradiative excitons with large in-plane wave vectors forming a so-called reservoir is experimentally studied in a high-quality semiconductor structure containing a 14…
Exciton energy oscillations induced by quantum beats
A. V. Trifonov, A. S. Kurdyubov, I. Ya. Gerlovin +5
In this paper, we experimentally demonstrate an oscillating energy shift of quantum-confined exciton levels in a semiconductor quantum well after excitation into a superposition of…
Exciton-polariton interference controlled by electric field
D. K. Loginov, P. A. Belov, V. G. Davydov +3
Linear in the wave-vector terms of an electron Hamiltonian play an important role in topological insulators and spintronic devices. Here we demonstrate how an external electric fie…
Subsecond nuclear spin dynamics in -GaAs
P. S. Sokolov, M. Yu. Petrov, K. V. Kavokin +5
We use time-resolved detection of the Hanle effect and polarized photoluminescence with dark intervals to investigate the buildup and decay of the spin polarization of nuclei inter…
Spin dynamics of quadrupole nuclei in InGaAs quantum dots
M. S. Kuznetsova, R. V. Cherbunin, I. Ya. Gerlovin +6
Photoluminescence polarization is experimentally studied for samples with (In,Ga)As/GaAs selfassembled quantum dots in transverse magnetic field (Hanle effect) under slow modulatio…
Inverse-phase Rabi oscillations in semiconductor microcavities
A. V. Trifonov, N. E. Kopteva, M. V. Durnev +7
We study experimentally the oscillations of a non stationary transient signal of a semiconductor microcavity with embedded InGaAs quantum wells. The oscillations occur as a result…
