Zero-phonon line emission of single photon emitters in helium-ion treated MoS
Katja Barthelmi, Tomer Amit, Mirco Troue +13
We explore the zero-phonon line of single photon emitters in helium-ion treated monolayer MoS, which are currently understood in terms of single sulfur-site vacancies. By compa…
Material-realistic modelling of quantum many-body effects in a monolayer TMDC nanolaser device
Joel Buchgeister, Alexander Steinhoff, Daniel Erben +2
The efficient light-matter interaction in combination with the small volume occupied by monolayer transition-metal dichalcogenides (TMDCs) makes this material class a notable optio…
Strategies for the alignment of electronic states in quantum-dot tunnel-injection lasers and their influence on the emission dynamics
Michael Lorke, Igor Khanonkin, Stephan Michael +3
In quantum-dot tunnel-injection lasers, the excited charge carriers are efficiently captured from the bulk states via an injector quantum well and then transferred into the quantum…
Carrier dynamics in quantum-dot tunnel-injection structures: microscopic theory and experiment
Michael Lorke, Igor Khanonkin, Stephan Michael +3
Tunneling-injection structures are incorporated in semiconductor lasers in order to overcome the fundamental dynamical limitation due to hot carrier injection by providing a carrie…
Electron dynamics in a 2D nanobubble: A two-level system based on spatial density
Roberto Rosati, Frank Lengers, Christian Carmesin +5
Nanobubbles formed in monolayers of transition metal dichalcogenides (TMDCs) on top of a substrate feature localized potentials, in which electrons can be captured. We show that th…
Optical nonlinearities in the excited carrier density of atomically thin transition metal dichalcogenides
Daniel Erben, Alexander Steinhoff, Michael Lorke +1
In atomically thin semiconductors based on transition metal dichalcogenides, photoexcitation can be used to generate high densities of electron-hole pairs. Due to optical nonlinear…
