The mesoscopic spin system formed by the 10 4–10 6 nuclear spins in a semiconductor
quantum dot offers a unique setting for the study of many-body spin physics in the …

▪ Abstract As a result of their fully quantized electronic states and high radiative efficiencies,
self-assembled quantum dots have enabled major advances in fundamental physics studies …

We review some electron transport experiments on few-electron, vertical quantum dot
devices. The measurement of current versus source-drain voltage and gate voltage is used …

Making use of self-assembly techniques, we realize nanoscopic semiconductor quantum
rings in which the electronic states are in the true quantum limit. We employ two …

We adopt an atomistic pseudopotential description of the electronic structure of self-
assembled, lens-shaped InAs quantum dots within the “linear combination of bulk bands” …

We have measured the vertical Stark effect of excitons confined to individual self-assembled
ring-shaped quantum dots. We find that the excitons have very large permanent dipole …

Tomographic nanometer-scale images of self-assembled InAs/GaAs quantum dots have
been obtained from surface-sensitive x-ray diffraction. Based on the three-dimensional …

We present a theoretical analysis of the mean electron and hole positions in self-assembled
InAs-GaAs quantum-dot structures. Because of the asymmetric dot shape, the electron …

Abstract Charged (X*) and neutral (X) exciton recombination is reported in the
photoluminescence spectra of single In (Ga) As quantum dots. Photoluminescence …

Self-assembled semiconductor quantum dots (QDs) exhibit fully quantized electronic states
and high radiative efficiencies. This makes them highly suitable both for fundamental …
