Effective long-range attraction of moiré excitons under the influence of atomic reconstructions and anisotropic screening
Nils-Erik Schütte, Carl Emil Mørch Nielsen, Niclas Götting +3
The moiré pattern, which emerges due to a relative rotation between two monolayers of transition metal dichalcogenides, features a long lattice period for small twist angles. The r…
Unconventional bright ground-state excitons in monolayer TiI from first-principles calculations
Franz Fischer, Carl Emil Mørch Nielsen, Marta Prada +1
Based on \textit{ab initio} screened configuration interaction calculations we find that TiI has a bright exciton ground state and identify two key mechanisms that lead to this…
Accurate force-field methodology capturing atomic reconstructions in transition metal dichalcogenide moiré systems
Carl Emil Mørch Nielsen, Miguel da Cruz, Abderrazak Torche +1
In this work, a generalized force-field methodology for the relaxation of large moiré heterostructures is proposed. The force-field parameters are optimized to accurately reproduce…
Optical Emission from Light-like and Particle-like Excitons in Monolayer Transition Metal Dichalcogenides
Mikkel Ohm Sauer, Carl Emil Mørch Nielsen, Lars Merring-Mikkelsen +1
Several monolayer transition metal dichalcogenides (TMDs) are direct band gap semiconductors and potentially efficient emitters in light emitting devices. Photons are emitted when…
