Materials for excitons–polaritons: Exploiting the diversity of semiconductors
摘要
The regime of strong coupling between photons and excitons gives rise to hybrid light–matter particles with fascinating properties and powerful implications for semiconductor quantum technologies. As the properties of excitons crucially depend on their host crystal, a rich field of exciton–polariton engineering opens by exploiting the diversity of semiconductors currently available. From dimensionality to binding energy to unusual orbitals, various materials provide different fundamental exciton properties that are often complementary, enabling vast engineering possibilities. This article aims to showcase some of the main materials for strong light–matter engineering, focusing on their fundamental complementarity and what this entails for future quantum technologies.
