Defect Candidates for Single-Photon Emission in Monolayer GaS and GaSe
Michael Lorke
We investigate the spin-resolved electronic structure of native vacancies and substitutional defects in monolayer GaS and GaSe using an anisotropic screened-exchange functional dev…
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…
