Exciton-Trion-Polaritons in Two-Dimensional Transition-Metal Dichalcogenides

Other Titles

Abstract

This dissertation covers a series of experiments that realized, investigated, and controlled exciton-trion-polaritons in transition-metal dichalcogenides (TMDs). First, theoretical and experimental research that led to the established understanding of trions are reviewed. Then, recent theoretical developments that led to a complete reimagining of excitons, trions, and their interactions with photons is discussed. With the theoretical background established, detailed measurements of optical conductivity of TMD MoSe2 are combined with quantitative analysis to determine the nature of strong Coulomb interactions between excitons and bound trions in TMDs. Then, design and simulations of, and measurements on a hybrid photonic-crystal-TMD structure is discussed whereupon remarkable agreement between experiment and theory evidences the existence of coherent exciton-trion-polariton formation. Initial experimental forays into electronic control of the optical properties of this polariton system is then reviewed. In the final chapter of this dissertation, a non-exhaustive investigation of potential device applications based on the understanding of exciton-trion-polaritons is conducted.
