## Description

- description: The spectrum of excitons in thin layers of semiconducting transition
    metal dichalcogenides (S-TMDs) is highly subject to the strong Coulomb electron-hole
    interaction in these materials and therefore does not follow the model system
    of a two-dimensional hydrogen atom. We investigate experimentally and theoretically
    excitonic properties in both the monolayer (ML) and the bilayer (BL) of MoSe2
    encapsulated in hexagonal BN. The measured magnetic field evolutions of the re-
    flectance contrast spectra of the MoSe2 ML and BL allow us to determine g-factors
    of intralayer A and B excitons, as well as the so-called "interlayer" exciton,
    which we compared with the theoretical values obtained using first-principle calculations.
    We demonstrate that the measured experimen- tally ladder of excitonic s states
    in the ML can be reproduced using the k · p approach with the Rytova-Keldysh potential
    that describes the electron-hole interaction. The analogous calculations for the
    BL case require taking into account out-of-plane dielectric response of the MoSe2
    BL, which is neglected for the ML.
