3D hydrogen-like screening effect on excitons in hBN-encapsulated monolayer transition metal dichalcogenides
Abstract We observe both s-series and p-series excitons by using sum frequency generation spectroscopy on monolayer (1L-)MX2 (M = Mo, W, X = S, Se) encapsulated by hexagonal boron nitride (hBN). Moreover, we perform numerical calculations with the Rytova-Keldysh potential and obtain the relative die...
