New results on bound excitons in quantum wells
(1997-12-01)
The formation of bound excitons (BE) is investigated for a GaAs/GaAlAs multiple quantum well (QW) system. The photoluminescence (PL) spectra are analysed as a function of the excitation energy. It was found that the carriers ...

Dispersion and damping of multiple quantum-well polaritons from resonant Brillouin scattering by folded acoustic modes
(American Physical Society, 2012-01)
We demonstrate that resonant Brillouin light scattering using ultranarrow lasers and high-resolution spectrometers provides unique access to the polariton lifetimes, a key parameter in their formation and dynamics. In very ...
Magneto-optical studies of the correlation between interface microroughness parameters and the photoluminescence line shape in GaAs/Ga0.7Al0.3As quantum wells
(1999-12-01)
In this work we analyze the relation between the interface microroughness and the full width at half maximum (FWHM) of the photoluminescence (PL) spectra for a GaAs/Ga0.7Al0.3As multiple quantum well (QW) system. We show ...
