High‐field magneto‐photoluminescence of semiconductor nanostructures

Abstract: We review the photoluminescence of semiconductor nanostructures in high magnetic fields, concentrating on the effects of the applied magnetic field on orbital motion (wave function extent), which is probed in experiments on large ensembles. We present an overview of the physics of excitons in high magnetic fields in 3- and 2-D before introducing the zero-dimensional case. We then discuss the physics of quantum-dot excitons in high magnetic fields with particular attention to the approximate analytical models u… Show more

“…29 In addition, the linewidth is expected to increase in disordered alloys. This behavior is due to the compression of the excitonic wavefunction under an increasing magnetic field, which causes the lineshape to be more susceptible to the local potential fluctuations resulting from compositional disorder.…”

“…The so-called excitonic model [36] was used to determine the exciton properties: diamagnetic shift coefficient Г, Bohr radius a B , and reduced mass μ. The model categorizes the magnetic field dependence of the PL into two regimes: low and high field.…”

“…Одними из наиболее изученных являются КТ халькогенидов металлов. Их синтезируют в виде порошков, пленок, в растворах, вводят в состав раз-личных матриц [4][5][6][7][8][9]. Размер КТ, как правило, находится в пределах 10 nm.…”

“…Их агрегаты достигают размера десят-ков нанометров [7,10,11]. Люминесценцию КТ связывают с излучательной рекомбинацией зарядов на уровнях структурно-примесных дефектов в объеме и на поверх-ности кристаллов [3][4][5][6]. Легирование кристаллов суще-ственно изменяет их оптические свойства.…”
