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…
Excitonic linewidth and coherence lifetime in monolayer transition metal dichalcogenides
Malte Selig, Gunnar Berghäuser, Archana Raja +7
Atomically thin transition metal dichalcogenides (TMDs) are direct-gap semiconductors with strong light-matter and Coulomb interaction. The latter accounts for tightly bound excito…
