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 on a magnetophotoluminescence study of single self-assembled semiconductor
nanorings which are fabricated by molecular-beam epitaxy combined with AsBr 3 in situ …

The Aharonov-Bohm effect in ring structures in the presence of electronic correlation and
disorder is an open issue. We report novel oscillations of a strongly correlated exciton pair …

We study analytically the optical properties of a simple model for an electron-hole pair on a
ring subjected to perpendicular magnetic flux and in-plane electric field. We show how to …

The optical exciton Aharonov-Bohm effect—ie, an oscillatory component in the energy of
optically active (bright) states—is investigated in nanorings. It is shown that a small effective …

We calculate the energy spectrum of semiconductor quantum rings. We consider a realistic
model consisting of rings with finite sizes and barrier potential and take into account an …

The ability to manipulate the coupling between quantum states in a controllable way has
become a major goal in the research of semiconductor-based quantum computation …

The transition energy, wave function and photoionization cross-section (PCS) in a Winternitz–
Smorodinsky potential quantum ring (QR) with a donor impurity subjected to a uniform …

We present a theoretical study of the energy spectrum of single electron and hole states in
quantum dots of annular geometry under a high magnetic field along the ring axis in the …

We theoretically investigate the optical functionality of a semiconducting quantum ring
manipulated by two electrostatic lateral gates used to induce a double quantum well along …
