Prospects and limitations of transition-metal dichalcogenide laser gain materials
Frederik Lohof, Alexander Steinhoff, Michael Lorke +4
Nanolasers operate with a minimal amount of active material and low losses. In this regime, single layers of transition-metal dichalcogenides (TMDs) are being investigated as next…
Observation of exciton redshift-blueshift crossover in monolayer WS2
Edbert J. Sie, Alexander Steinhoff, Christopher Gies +10
We report a rare atom-like interaction between excitons in monolayer WS2, measured using ultrafast absorption spectroscopy. At increasing excitation density, the exciton resonance…
Excitation-induced transition to indirect band gaps in atomically thin transition metal dichalcogenide semiconductors
D. Erben, A. Steinhoff, G. Schönhoff +3
Monolayers of transition metal dichalcogenides (TMDCs) exhibit an exceptionally strong Coulomb interaction between charge carriers due to the two-dimensional carrier confinement in…
Frequency-dependent substrate screening of excitons in atomically thin transition metal dichalcogenide semiconductors
A. Steinhoff, T. O. Wehling, M. Rösner
Atomically thin layers of transition metal dichalcogenides (TMDCs) exhibit exceptionally strong Coulomb interaction between charge carriers due to the two-dimensional carrier confi…
