This review article provides an overview of recent advances in the study and understanding
of dynamics of excitons in semiconductor nanocrystals (NCs) or quantum dots (QDs) …

High-sensitivity femtosecond transient absorption is applied to directly measure the
population-depopulation dynamics of the lowest (1 S) and the first excited (1 P) electron …

The relaxation of the 1 P to 1 S electronic states of CdSe semiconductor nanocrystals is
followed by infrared pump-probe spectroscopy. Fast (1 ps) and slow (> 200 ps) components …

Excited states and energy relaxation processes are studied for stacked InAs/GaAs QD's with
GaAs cap layers grown by migration enhanced epitaxy. Photoluminescence excitation (PLE) …

The effect of phonon bottleneck on quantum-dot laser performance is examined by solving
the carrier-photon rate equations including the carrier relaxation process into the quantum …

We applied low-temperature diffraction-limited confocal optical microscopy to spatially
resolve and spectroscopically study photoluminescence from single self-assembled …

A systematic study of exciton dynamics is presented in quantum boxes formed naturally
along the axis of a V-shaped quantum wire, by means of time and spatially resolved …

The quantum size effect of exciton transitions is investigated experimentally and theoretically
for self-organized InAs/GaAs quantum dots (QD's). Photoluminescence excitation (PLE) …

This article discusses the hot charge carriers in semiconductor quantum dots (QDs): their
generation, relaxation, extraction and applications in different technologically relevant areas …

Within this work we present optical and structural properties of InP quantum dots embedded
in (Al x Ga 1− x) 0.51 In 0.49 P barriers. Atomic force microscopy measurements show a …
