Dielectric Engineering of Electronic Correlations in a van der Waals Heterostructure
Philipp Steinleitner, Philipp Merkl, Alexander Graf +10
Heterostructures of van der Waals bonded layered materials offer unique means to tailor dielectric screening with atomic-layer precision, opening a fertile field of fundamental res…
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…
Mapping of the dark exciton landscape in transition metal dichalcogenides
Gunnar Berghäuser, Philipp Steinleitner, Philipp Merkl +3
Transition metal dichalcogenides (TMDs) exhibit a remarkable exciton physics including optically accessible (bright) as well as spin- and momentum-forbidden (dark) excitonic states…
Out of the dark and into the light: towards dark-state based chemical sensors
Maja Feierabend, Gunnar Berghäuser, Andreas Knorr +1
The rapidly increasing use of sensors throughout different research disciplines and the demand for more efficient devices with less power consumption depends critically on the emer…
Optical fingerprint of dark 2p-states in transition metal dichalcogenides
Gunnar Berghäuser, Andreas Knorr, Ermin Malic
We present a microscopic study on higher excitonic states in transition metal dichalcogenides in the presence of disorder. We show that the geometric phase cancels the degeneration…
