Abstract Quantum dots,,,,,, or 'artificial atoms' are of fundamental and technological interest—
for example, quantum dots, may form the basis of new generations of lasers. The emission in …

We investigate factors which control the optical properties of quantum dots filled with N
excitons. Detailed calculation of the electronic structure of these excitonic artificial atoms is …

The self-assembly of semiconductor quantum dots has opened up new opportunities in
photonics. Quantum dots are usually described as 'artificial atoms', because electron and …

The strength of radiative transitions in atoms is governed by selection rules that depend on
the occupation of atomic orbitals with electrons. Experiments have shown,,, similar electron …

We report on the observation of photoluminescence from positive, neutral, and negative
charge states of single semiconductor quantum dots. For this purpose we designed a …

This book deals with the electronic and optical properties of two low-dimensional systems:
quantum dots and quantum antidots and is divided into two parts. Part one is a self …

Quantum dots or rings are artificial nanometre-sized clusters that confine electrons in all
three directions. They can be fabricated in a semiconductor system by embedding an island …

Atomic physics progressed rapidly at the beginning of the last century, thanks, in large part,
to optical spectroscopy. Quantization and spin were discovered through optical studies, as …

An atom can be thought of as a spherically symmetric box for electrons, where the walls of
the box are set by the attraction of the electrons to the positively charged nucleus. The …
