Theory of Excitons and Excitonic Devices
Indirect excitons are bound pairs of electrons and holes confined in adjacent quantum wells of a semiconductor nanostructure. Indirect excitons are dipoles and their energy can be controlled in situ by an external voltage. This property makes it possible to realize excitonic devices. These devices can be much more energy efficient than conventional electronics because of remarkably long lifetime of indirect excitons and their bosonic nature. I will overview the current state-of-the-art of excitonic devices in different semiconductor materials (inorganic, organic, van der Waals) and outline future challenges. I will also discuss open fundamental physics questions of indirect excitons including coherence and condensation, localization-delocalization transition, and exciton correlations.
