Recently, the measurement of binding energy of excitons in the two-dimensional physics systems such as graphene or transition-metal dichalcogenides (TMDs) is of great interest. In this work, the FK operator method combined with the Laplace transformation is used to calculate the energy spectra of the negatively charged exciton in atomic monolayers with the presence of a magnetic field. The obtained results are well compared with the other numerical methods and will be used for analyzing some experiments carried out for the considered system. Particularly, the magnetic enhancement of the screening effect for the Coulomb interaction in the TMD monolayer WS2 will be investigated.
