Molecule signatures in photoluminescence spectra of transition metal dichalcogenides
Maja Feierabend, Gunnar Berghaeuser, Malte Selig +4
Monolayer transition metal dichalcogenides (TMDs) show an optimal surface-to-volume ratio and are thus promising candidates for novel molecule sensor devices. It was recently predi…
Exciton Relaxation Cascade in Two-dimensional Transition-metal dichalcogenides
Samuel Brem, Gunnar Berghaeuser, Malte Selig +1
Monolayers of transition-metal dichalcogenides (TMDs) are characterized by an extraordinarily strong Coulomb interaction giving rise to tightly bound excitons with binding energies…
Phonon Sidebands in Transition Metal Dichalcogenides
Dominik Christiansen, Malte Selig, Gunnar Berghäuser +8
Excitons dominate the optical properties of monolayer transition metal dichalcogenides (TMDs). Besides optically accessible bright exciton states, TMDs exhibit also a multitude of…
The role of momentum-dark excitons in the elementary optical response of bilayer WSe
Jessica Lindlau, Malte Selig, Andre Neumann +6
Monolayer (ML) transition metal dichalcogenides (TMDs) undergo substantial changes in the single-particle band structure and excitonic optical response upon the addition of just on…
Dark excitons in transition metal dichalcogenides
Ermin Malic, Malte Selig, Maja Feierabend +5
Monolayer transition metal dichalcogenides (TMDs) exhibit a remarkably strong Coulomb interaction that manifests in tightly bound excitons. Due to the complex electronic band struc…
Dark and bright exciton formation, thermalization, and photoluminescence in monolayer transition metal dichalcogenides
Malte Selig, Gunnar Berghäuser, Marten Richter +3
The remarkably strong Coulomb interaction in atomically thin transition metal dichalcogenides (TMDs) results in an extraordinarily rich many-particle physics including the formatio…
