Exciton Ultrafast Dynamics in Nanomaterials
Category
Published on
Abstract
The optical and electrical properties of nanomaterials arise from their excitons, which are bound electron-hole pairs. Because of the nm-size confinement, excitonic effects on the optical and electrical properties of the nanomaterial are enhanced. In this talk, I will present our experimental capabilities to study nanomaterials. In particular, femtosecond laser spectroscopy and microscopy will be discussed. Additionally, I will present some of our recent publications by undergraduate students in the topic of exciton ultrafast dynamics in atomically-thin two-dimensional transition metal dichalcogenides (2D-TMD).
