Self-assembled nanostructures, such as quantum dots (QDs), quantum rings (QRs) and
nanowires (NWs), have been extensively studied because of their physical properties and …

Making use of a droplet-epitaxial technique, we realize nanometer-sized quantum ring
complexes, consisting of a well-defined inner ring and an outer ring. Electronic structure …

We report the direct measurement of the persistent current carried by a single electron by
means of magnetization experiments on self-assembled InAs/GaAs quantum rings. We …

A microscopic picture for the GaAs overgrowth of self-organized InAs/GaAs (001) quantum
dots is developed. Scanning tunneling microscopy measurements reveal two cap** …

We present an atomic-scale analysis of the indium distribution of self-assembled In (Ga) As
quantum rings (QRs) which are formed from InAs quantum dots by cap** with a thin layer …

Several distinctive self-assembled InGaAs quantum dot molecules (QDMs) are studied. The
QDMs self-assemble around nanoscale-sized GaAs moundlike templates fabricated by …

Intensive research on fullerenes, nanoparticles, and quantum dots in the 1990s led to
interest in nanotubes and nanowires in subsequent years. Handbook of Nanophysics …

We analyze theoretically the electron energy spectrum and the magnetization of an electron
in a strained In x Ga 1− x As∕ Ga As self-assembled quantum ring (SAQR) with realistic …

Recently, very thin AlAs cap** layers (CLs) have been proposed as a useful tool to
increase the performance of InAs/GaAs quantum dot (QDs) devices. However, the structure …

One-electron states in a toroidal quantum dot in the presence of an external magnetic field
have been considered. The magnetic field operator and the Schrodinger equation have …
