Digital-Alloy Bragg Mirrors in High-Q Microcavities for Polariton Lasing
V. A. Stolyarov, A. S. Kurdyubov, A. V. Trifonov +7
We present an approach to the molecular-beam epitaxy of high-Q planar GaAs-based microcavities in which the AlGaAs high-index layers of the distributed Bragg reflectors (DBRs) are…
Effect of electric field on excitons in wide quantum wells
Shiming Zheng, E. S. Khramtsov, I. V. Ignatiev
A microscopic model of a heterostructure with a quantum well (QW) is proposed to study the exciton behavior in an external electric field. The effect of an electric field ranging f…
Exciton dynamics in CdTe/CdZnTe quantum well
A. V. Mikhailov, A. S. Kurdyubov, E. S. Khramtsov +6
Exciton energy structure and population dynamics in a wide CdTe/CdZnTe quantum well are studied by spectrally-resolved pump-probe spectroscopy. Multiple excitonic resonances in ref…
Nonlinear behaviour of the nonradiative exciton reservoir in quantum wells
A. S. Kurdyubov, A. V. Trifonov, A. V. Mikhailov +4
Excitons and free charge carriers with large wave vectors form a nonradiative reservoir, which can strongly affect properties of bright excitons due to the exciton-exciton and exci…
Exciton-exciton and exciton-charge carrier interaction and the exciton collisional broadening in GaAs/AlGaAs quantum wells
B. F. Gribakin, E. S. Khramtsov, A. V. Trifonov +1
Wave functions of heavy-hole excitons in GaAs/AlGaAs square quantum wells (QWs) of various widths are calculated by the direct numerical solution of a three-dimensi…
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…
