Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

Ultrathin insertions of a narrow band‐gap material in wide band‐gap matrices represent a
challenging medium in view of aspects of growth phenomena, unique optical properties, and …

In 1954, Dicke pointed out that the description of a spontaneously radiating gas has to
include the fact that all atoms or molecules interact with a common radiation field …

We study the electronic structure of ultrathin zinc-blende two-dimensional (2D)-CdSe
nanosheets both theoretically, by Hartree-renormalized k· p calculations including Coulomb …

The influence of quantum dot (QD) asymmetry on the emission of single three-dimensionally
confined biexcitons in II-VI semiconductor nanostructures has been studied by …

The general trend in modern solid state physics and technology is to make things smaller.
The size of key elements in modern devices approaches the nanometer scale, for both …

The decay characteristics of excitons and biexcitons in one single semiconductor quantum
dot (QD) are directly monitored using time-and spatially resolved photoluminescence …

The quantum-confined Stark effect in a single self-assembled CdSe/ZnSe quantum dot was
studied by means of highly spatially resolved photoluminescence spectroscopy. A …

We report on reversible spectral shifts in the emission spectra of self-organized CdSe single
quantum dots on a time scale of seconds. Energy shifts of up to 3.5 meV have been …

A transmission electron microscopy (TEM) study of the structure and chemical composition
of 0.5 to 3.0 ML (monolayer) CdSe sheets that are buried in a ZnSe matrix is presented. The …
