TL;DR: In this paper, the authors used current transient spectroscopy (OTCS) to give the electrical characteristics of traps in semi-insulating material, as classic DLTS is in n- or p-type semiconductors.

TL;DR: In this article, the authors theoretically investigated the intersubband relaxation of electrons in quantum well systems during photoexcitation using an ensemble Monte Carlo approach, and found excellent agreement between the simulated decay time of the n = 2 subband, and the experimental photoluminescence decay, although it is difficult to distinguish the pure decay time due to electron-electron scattering versus that due to polar optical phonons caused by carrier heating effects.

TL;DR: In this paper, the authors studied the mechanisms of capture and inter-subband relaxation in quantum wells by time resolved luminescence with subpicosecond resolution and showed that the quantum mechanical capture time does not show strong oscillations due to the competing influence of different capture mechanisms.

TL;DR: In this paper, the anisotropic two-photon absorption spectra of an AlGaAs-GaAs V-shaped quantum wire with realistic band structure, including excitonic effects, were calculated by integrating effective multiband Bloch equations accounting for the Coulomb interaction within the Hartree-Fock approximation.

TL;DR: In this paper, a phase-locked spectroscopic technique was used to investigate the coherent dynamics of exciton-polaritons and excitons in semiconductor quantum nanostructures.
