Investigating excitonic physics in two-dimensional semiconductors by coherent two-dimensional microscopy

Abstract

© 2020 OSA - The Optical Society. All rights reserved. Excitonic interactions determine the photoelectric properties of two-dimensional semiconductors. By using spatially resolved coherent two-dimensional micro-spectroscopy, we are able to determine the strength of exciton-phonon coupling in single-layer MoSe2 at room temperature
