Exciton storage in a nano-scale Aharonov-Bohm ring with electric field tuning
arXiv:0809.3863 · doi:10.1103/PhysRevLett.102.096405
Abstract
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 tune this excitonic system from optically active to optically dark as a function of these external fields. Our results offer a simple mechanism for exciton storage and read-out.
