In this article we review the extensive experimental work on the compositional mapping of semiconductor quantum dots and rings. After a brief introduction of the various experimental …
We investigate theoretically the electron states in HgTe quantum dots (QDs) with inverted band structures. In sharp contrast to conventional semiconductor quantum dots, the quantum …

Most commonly used for the self‐assembling of InGaN quantum dots is a Stranski– Krastanov growth scheme. Often neglected is the influence of spinodal decomposition …
Exciton inter-and intra-actions in a GaAs/AlGaAs quantum well (QW) and quantum dot (QD) ensemble are studied using optical two-dimensional Fourier transform spectroscopy. We …
We investigated the photoluminescence from InP quantum dots incorporated in (Ga 0.51 In 0.49) P microdisk structures. With increasing pump power we observe a transition to …
