The linear and non-linear optical absorption coefficients of a D 2+ artificial molecule
confined in GaAs nano-scaled rings under a threading magnetic field were calculated. The …

The features of electron-donor-impurity energy spectrum and related optical response in
GaAs-AlGaAs concentric double quantum rings are investigated. The geometrical shape of …

Understanding the optical emission characteristics of semiconductor nanostructures is
important when determining their device applicability. Their emission depends on the …

We theoretically investigate the properties of an electron energy spectrum in a double GaAs-
Al0. 3Ga0. 7As quantum ring by using the effective mass and adiabatic approximations …

In this article, we report the formation of InAs quantum ring nanostructures (QRNs) on GaSb
(0 0 1) surface by droplet epitaxy (DE) mode using molecular beam epitaxy. We examined …

We demonstrate a new route toward the integration and deterministic placement of quantum
dots (QDs) within prepatterned nanostructures. Using standard electron-beam lithography …

We demonstrate experimentally the submicron size self-assembled (SA) GaAs quantum
rings (QRs) by quantum size effect (QSE). An ultrathin In 0.1 Ga 0.9 As layer with different …

We theoretically investigate suppression and recovery of the Aharonov-Bohm oscillations of
the diamagnetic response of electrons (holes) confined in self-assembled In c Ga 1− c …

We show that the repulsive core of semiconductor quantum rings enhances the heavy hole-
light hole mixing. Calculations for InAs/GaAs quantum rings show that the light hole …
