Abstract
Monolayer transiton-metal dichalcogenides (TMDs) have attracted wide attention over the last several years due to their interesting optical properties and promising applications in spintronics, valleytronics, optoelectronics, and energy harvesting [1,2]. In this talk, we present a new Coulomb potential for TMDs, which not only captures the nonhydrogenic Rydberg series of exciton binding energies, but also correctly describes the weak dependence of the trion binding energy on the dielectric materials below and on top of the monolayer [3]. In addition, we explain how various many-body interactions affect the spectrum of monolayer TMDs [4], with emphasis on the coupling between neutral excitons and shortwave plasmons that originate from the spin-split conduction-band valleys [5]. Finally, we explain how exciton-phonon interactions affect the optical emission spectrum in these materials. [1] J.R. Schaibley, et al., Nature Reviews Materials 1, 16055 (2016). [2] S.
