Aharonov-bohm effect for neutral excitons in quantum rings

Abstract

Quantum interference patterns predicted by theory due to the finite structure of neutral excitons in InAs quantum rings are corroborated experimentally in the magneto-photoluminescence spectra of these nanostructures. The effects associated to built in electric fields and to the temperature on these Aharonov-Bohm-like oscillations are described and confirmed by complementary experimental procedures.
