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^*…
Nonlinear effects in many-body van der Waals interactions

Twisted bilayered graphenes at magic angles are systems housing long ranged periodicity of Moiré pattern together with short ranged periodicity associated with the individual graph…
Thermal effect on magnetoexciton energy spectra in monolayer transition metal dichalcogenides
Duy-Nhat Ly, Dai-Nam Le, Ngoc-Hung Phan +1
It is widely comprehended that temperature may cause phonon-exciton scattering, enhancing the energy level's linewidth and leading to some spectrum shifts. However, in the present…
Dispersive interactions between standard and Dirac materials and the role of dimensionality
Dai-Nam Le, Pablo Rodriguez-Lopez, Lilia M. Woods
The van der Waals (vdW) interaction plays a prominent role between neutral objects at separations where short ranged chemical forces are negligible. This type of dispersive couplin…
