Abstract

This talk will discuss our recent work on optical phenomena and electronic phenomena in 2D semiconductors when they are placed in close proximity on plasmonic substrates such as Au, Ag and Al. I will also show how using a plasmonic tip once can use near-field tip based micro-spectroscopy to probe defects, interfaces, strain and hybrid states in 2D excitonic semiconductors and junctions. If time permits, I will also present how 1D nanostructuring of MoS2, WS2, WSe2 etc. into nanophotonic dielectric gratings can enable exploration of new regimes of light-matter confinement including formation of hybrid exciton-plasmon-polariton states. I will extend this concept to 2D hybrid perovskites and superlattices.
