Probing Dark Excitons in Monolayer MoS by NonLinear Two-Photon Spectroscopy
Chenjiang Qian, Viviana Villafañe, Pedro Soubelet +3
We report a new dark exciton in monolayer MoS using second harmonic generation spectroscopy. Hereby, the spectrally dependent second harmonic generation intensity splits into t…
Nonlinear Dispersion Relation and Out-of-Plane Second Harmonic Generation in MoSSe and WSSe Janus Monolayers
Marko M. Petrić, Viviana Villafañe, Paul Herrmann +9
Janus transition metal dichalcogenides are an emerging class of atomically thin materials with engineered broken mirror symmetry that gives rise to long-lived dipolar excitons, Ras…
Lasing of Moiré Trapped MoSe/WSe Interlayer Excitons Coupled to a Nanocavity
Chenjiang Qian, Mirco Troue, Johannes Figueiredo +8
We report lasing of moiré trapped interlayer excitons (IXs) by integrating a pristine hBN-encapsulated MoSe/WSe heterobilayer into a high- () nanophotonic cavity.…
