摘要：

The behavior of electrons, excitons, and charged electron-hole complexes in quantum rings is studied taking into account radial vibrations in a magnetic field. The diamagnetic shift of the exciton luminescence line is found to be positive for a neutral exciton and negative for a trion and all other charged complexes. It is shown that the magnetic-field dependent component of the electron ring energy does not depend on the electron-electron interaction. (C) 2001 MAIK "Nauka/Interperiodica".
