Talk Title: Nanoimprinted scanning probe for nanoscale optical mapping on 2D excitons and plexcitons
Zoom link
Abstract:
2D Excitons, found in atomically thin materials, possess remarkable optical properties and versatile functionalities, opening new forefronts in nanoscale light-matter interactions. Our research centers on developing Tip-enhanced spectroscopies (or scanning near-field optical microscopes) to achieve nanoscale optical mappings of these excitons under ambient conditions. We address key challenges from near-field probe fabrication to advanced heterostructure design. In this talk, I will first present a facile and reproducible probe design crafted with nanoimprinting techniques. The second part will explore the photophysics of 2D materials and the interactions between excitons and plasmonic cavities, leading to the plexciton formation.
