Key Points

The study aims to explore the photoluminescence spectra of symmetrically and asymmetrically doped quantum wells, focusing on magnetoplasmon features.
Examined photoluminescence spectra in symmetrically and asymmetrically doped GaAs/AlGaAs quantum wells.
Identified additional maxima in the spectra related to magnetoplasmic replicas of optical transitions.
Analyzed connections between observed features and existing transport and optical studies.
Additional peaks were detected in the spectra, specifically in the symmetrically doped quantum wells.
The maxima correspond to Van Hove singularities in the density of states of magnetoplasmons.
The findings enhance the understanding of optoelectronic properties in high mobility heterostructures.

Abstract

Исследованы спектры фотолюминесценции симметрично и несимметрично легированных квантовых ям в высокоподвижных гетероструктурах GaAs/AlGaAs. Обнаружены дополнительные максимумы в магнетоплазменной реплике основного оптического перехода из зоны проводимости в подзону тяжелых дырок валентной зоны симметрично легированной квантовой ямы на факторе заполнения электронов ν = 1. Максимумы в спектре фотолюминесценции связываются с сингулярностями Ван Хова в функции плотности состояний магнетоплазмонов от энергии. Обсуждается связь наблюдаемых особенностей в спектре фотолюминесценции с известными транспортными и оптическими исследованиями.
