Nonlinear optics and transport of excitons in transition metal dichalcogenides monolayers

(Nanostructures quantiques propriétés optiques)


Sommaire:

Monolayers of transition metal dichalcogenides (TMDs) with MoS2 and WSe2 being the prominent examples are actively studied nowadays. These materials demonstrate remarkable optical properties controlled by the robust excitons, Coulomb-correlated electron-hole pairs, with the binding energies on the order of several hundreds millielectronvolts. In semiconductors, Wannier-Mott excitons form a series of 1s, 2s, 2p, … hydrogen-like states. In TMD monolayers the binding energies of the excitonic states strongly differ from the two-dimensional hydrogen atom model.
In my talk, the nonlinear optical and transport effects of excitons in TMD monolayers are discussed.
