Two-dimensional excitons in monolayer transition metal dichalcogenides from simple models and variational calculations
Jian-zhong Zhang, Jin-zhong Ma
Exciton spectra of monolayer transition metal dichalcogenides (TMDs) in various dielectric environments are studied. The screened hydrogen model (SHM) [Phys. Rev. Lett. 116, 056401…
