Abstract

Using the Modulated Perturbation Method (MPM) in the second approximation order to solve the Schrodinger equation, we get the analytical description for excitons for the ground state in monolayer transition metal dichalcogenide (TMDC). The results obtained are generalizable to many different types of TMDC. The accuracy test for two types of TMDC is WSe2  and WS2 by comparison with the exact numerical solutions shows that the error of the analytical description is less than 0.5%. This is a significant result and promising for further research for higher excited states.
