Analytical Retrieval of Material Parameters in Monolayer Transition-Metal Dichalcogenides Based on a Solvable Exciton Model
Duy-Nhat Ly, Thanh-Son Nguyen, Ngoc-Tram D. Hoang +1
We develop an analytical procedure to retrieve fundamental material parameters of monolayer transition-metal dichalcogenides from optical and magneto-optical exciton spectra, based…
Anisotropic two-dimensional magnetoexciton with exact center-of-mass separation
Dang-Khoa D. Le, Hoang-Viet Le, Dai-Nam Le +4
Excitons in anisotropic two-dimensional (2D) materials, defined by direction-dependent effective masses, are of pronounced interest for their roles in excitonic and magneto-optical…
Retrieval of fundamental material parameters of monolayer transition metal dichalcogenides from experimental exciton energies: An analytical approach
Duy-Nhat Ly, Dai-Nam Le, Dang-Khoa D. Le +1
We propose a straightforward and highly accurate method for extracting material parameters such as screening length, bandgap energy, exciton reduced mass, and the dielectric consta…
Analytical exciton energies in monolayer transition-metal dichalcogenides
Hanh T. Dinh, Ngoc-Hung Phan, Duy-Nhat Ly +5
We derive an analytical expression for -state exciton energies in monolayer transition-metal dichalcogenides (TMDCs): $E_{\text{ns}}=-{\text{Ry}}^*\times P_n/{(n-1/2+0.479\, r^*…
