Colloidal quantum dots (QDs) are nanoscale semiconductor crystals with surface ligands
that enable their dispersion in solvents. Quantum confinement effects facilitate wave function …

Replacing a single atom of a host semiconductor nanocrystal with a functional dopant can
introduce completely new properties potentially valuable for “solotronic” information …

Impurity doping can be used to dramatically alter the physical properties of semiconductor
nanostructures and endow them with promising new technological potential. This review …

Single impurities with nonzero spin and multiple ground states offer a degree of freedom that
can be utilized to store the quantum information. However, Fe2+ dopant is known for having …

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 …

We report on the coherent dynamics of the spin of an individual magnetic atom coupled to
carriers in a semiconductor quantum dot which has been investigated by resonant …

Effective and unrestricted engineering of atom–photon interactions requires precise spatially
resolved control of light beams. The significant potential of such manipulations lies in a set of …

We report on properties of an optical microcavity based on (Cd, Zn, Mg) Te layers and
embedding (Cd, Zn) Te quantum wells. The key point of the structure design is the lattice …

We demonstrate optical spin orientation of an individual Mn 2+ ion embedded in a
CdSe/ZnSe quantum dot. It is achieved through the injection of spin-polarized excitons to the …

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 …
