Confinement effects on multiexciton dynamics in semiconductor nanocrystals

Colloidal semiconductor nanocrystals are a promising platform for a number of technological developments in a wide variety of lighting applications. They also are an incredibly useful model system to interrogate fundamental carrier interactions in crystalline semiconductor lattices. This thesis investigates the properties of multiexciton states in semiconductor nanocrystals to build an understanding of what drives their emission dynamics and efficiency. A complete understanding of the processes which dominate in a wide variety of nanocrystal systems sheds light on electron-hole and exciton-exciton interactions and provides guidance on how to engineer nanocrystals for particular applications. In the first two chapters, I will build a foundation of understanding of semiconductor nanocrystal systems, and how to build up an intuitive understanding of the states in question from both fundamental modeling and chemical intuition.
