Analytical exciton energies in monolayer transition-metal dichalcogenides

Hanh T. Dinh, Ngoc-Hung Phan, Duy-Nhat Ly +5

We derive an analytical expression for $s$-state exciton energies in monolayer transition-metal dichalcogenides (TMDCs): $E_{\text{ns}}=-{\text{Ry}}^*\times P_n/{(n-1/2+0.479\, r^*…
