Impurity effects on the Aharonov-Bohm optical signatures of neutral quantum-ring magnetoexcitons
Impurity effects on the Aharonov-Bohm optical signatures of neutral quantum-ring magnetoexcitons
We study the role of impurity scattering on the photoluminescence (PL) emission of polarized magnetoexcitons. We consider systems where both the electron and hole are confined on a ring structure (quantum rings) as well as on a type-II quantum dot. Despite their neutral character, excitons exhibit strong modulation of energy …
