Over the past decade, Rydberg excitons in 2D semiconductors have attracted much attention for potential applications in quantum technologies. Here, we study Rydberg excitons in monolayer transition-metal dichalcogenide (TMD) semiconductors. We determine exciton binding energies and sizes in monolayer TMDs by using the variational method, and show the influences of the surrounding dielectric environment on the exciton properties.
