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…
Magnetic brightening of light-like excitons in a monolayer semiconductor
A. Delhomme, T. Amit, P. Ji +4
Monolayer transition-metal dichalcogenides, such as WSe, are direct gap, multi-valley semiconductors. Long-range electron-hole exchange interactions mix the valleys, yielding d…
Generalized many-body exciton g-factors: magnetic hybridization and non-monotonic Rydberg series in monolayer WSe
Paulo E. Faria Junior, Daniel Hernangómez-Pérez, Tomer Amit +2
Magneto-optics of low dimensional semiconductors, such as monolayer transition metal dichalcogenides, offers a vast playground for exploring complex quantum phenomena. However, cur…
Defect-Bound Excitons in Topological Materials
Roni Majlin Skiff, Sivan Refaely-Abramson, Raquel Queiroz +1
Excitons, bound states of electrons and holes, are affected by the properties of the underlying band structure of a material. Defects in lattice systems may trap electronic defect…
Spectrally resolved far-field emission pattern of single photon emitters in MoS2
Katja Barthelmi, Tomer Amit, Lukas Sigl +9
We explore the optical dipole orientation of single photon emitters in monolayer MoS2 as produced by a focused helium ion beam. The single photon emitters can be understood as sing…
Reduced absorption due to defect-localized interlayer excitons in transition metal dichalcogenide-graphene heterostructures
Daniel Hernangómez-Pérez, Amir Kleiner, Sivan Refaely-Abramson
Associating the presence of atomic vacancies to excited-state transport phenomena in two dimensional semiconductors is of emerging interest, and demands detailed understanding of t…
