Charged excitons and cavity polaritons
01 October 2001
When a quantum well containing a low density two-dimensional electron gas is embedded in a microcavity, the photoexcited charged excitons that interact with the confined photons form charged polaritons, The objective of this paper is to describe the experimental spectroscopic evidence for the appearance of charged microcavity polaritons, and the analysis of their energy and oscillator strength dependence on the 2DEG density. Then, the model calculations are extended to predict that the charged polaritonic signal can be electrically drifted in the QW plane over measurable distances.
