Solotronics, optoelectronics based on solitary dopants, is an emerging field of research and
technology reaching the ultimate limit of miniaturization. It aims at exploiting quantum …

In light science and applications, equally important roles are played by efficient light
emitters/detectors and by the optical elements responsible for light extraction and delivery …

We demonstrate evidence for a radiative recombination channel of dark excitons in self-
assembled quantum dots. This channel is due to a light hole admixture in the excitonic …

The quantum confinement in a typical quantum dot (QD) is determined primarily by the
nanosystem's dimensions and average composition. We demonstrate, however, that …

Absorption spectra of neutral, negatively, and positively charged semiconductor quantum
dots are studied theoretically. We provide an overview of the main energetic structure …

We study the biexciton formation process in a single CdTe/ZnTe quantum dot. Consistently
with previous studies, we find subquadratic dependence of the biexciton photoluminescence …

Because of their weak coupling to the electromagnetic field, dark excitons in semiconductor
quantum dots possess extremely long lifetimes, which makes them attractive candidates for …

The structure of the ground-state exciton of Cd (Se, Te) quantum dots embedded in ZnTe
matrix is studied experimentally using photoluminescence spectroscopy and theoretically …

Self-assembled Cd (Se, Te) quantum dots with various Se compositions embedded in the
ZnTe matrix are grown by molecular beam epitaxy. A huge redshift of the near band edge …

We present the study of the spin-lattice relaxation of an isolated Mn 2+ ion in a single
CdTe/ZnTe quantum dot. The measurements are done in a wide range of magnetic field …
