Colloidal semiconductor nanocrystals become increasingly important in materials science
and technology, due to their optoelectronic properties that are tunable by size. The …

We demonstrate the large potential of III–V compound semiconductors for a novel type of
Flash memory. The concept is based on self-organized III–V quantum dots (QDs). Here the …

We present an InAs/GaAs quantum dot (QD) memory structure with all-electrical data access
which uses holes as charge carriers. Charging and discharging of the QDs are clearly …

We present a cross-sectional scanning tunneling microscopy study of GaSb/GaAs quantum
dots grown by molecular beam epitaxy. Various nanostructures are observed as a function …

Self-assembled quantum dots are still one of the best model systems for artificial atoms in a
solid-state environment, where the electronic states can be accessed by electrical and …

Using time-resolved transconductance spectroscopy, we study the tunneling dynamics
between a two-dimensional electron gas (2DEG) and self-assembled quantum dots (QDs) …

Self-assembled quantum dots (QDs) are prominent candidates for solid-state quantum
information processing. For these systems, great progress has been made in addressing …

This paper investigates the effects of Coulomb interactions on the emission dynamics of Sb-
containing quantum dot (QD) systems under high excitation densities. Two different type-II …

Rolled-up nanomembrane electrodes are used to prepare optically transparent Au/TiO 2
Schottky diodes suitable for deep level transient photocapacitance spectroscopy. It is …

In this work, we investigate high-mobility two-dimensional electron gases in Al x Ga 1-x As
heterostructures by employing Schottky-gate-dependent measurements of the samples' …
