Abstract

In present study, we develop an effective and universal technique for retrieving dispersion of bulk and monolayer TMDs from spectroscopic ellipsometry measurements. The basis of the method is excitonic nature of the dispersion. In addition, we demonstrate beneficial influence of annealing on optical properties of MoS2.
