Abstract
Electronic states of a singly ionized double donor system (D 2 +) confined in a nanostructure with a ring-like geometry in a threading magnetic field are calculated. Solutions of the Schrödinger equation are obtained by variational separation of variables in the adiabatic limit. Numerical results are shown for bonding and anti-bonding lowest-lying molecular states corresponding to different relative locations of the coupled impurities. We show that displacement of donors from the axis toward the ring and decrease in the angle between their position vectors may strongly affect the Aharonov–Bohm oscillations of the far-infrared spectra and produce a quenching of oscillations of the lower energy levels.
