Ultra-Sensitive Extinction Measurements of Optically Active Defects in Monolayer MoS
Florian Sigger, Ines Amersdorffer, Alexander Hötger +12
We utilize cavity-enhanced extinction spectroscopy to directly quantify the optical absorption of defects in MoS generated by helium ion bombardment. We achieve hyperspectral i…
Lattice reconstruction in MoSe-WSe heterobilayers synthesized by chemical vapor deposition
Zhijie Li, Farsane Tabataba-Vakili, Shen Zhao +11
Vertical van der Waals heterostructures of semiconducting transition metal dichalcogenides realize moiré systems with rich correlated electron phases and moiré exciton phenomena. F…
Coulomb-correlated states of moiré excitons and charges in a semiconductor moiré lattice
Borislav Polovnikov, Johannes Scherzer, Subhradeep Misra +10
Semiconductor moiré heterostructures exhibit rich correlation-induced many-body phenomena with signatures of emergent magnetism, Mott insulating states or generalized Wigner crysta…
Excitons in mesoscopically reconstructed moiré heterostructures
Shen Zhao, Zhijie Li, Xin Huang +9
Moiré effects in twisted or lattice-incommensurate vertical assemblies of two-dimensional crystals give rise to a new class of quantum materials with rich transport and optical phe…
Energy dispersive X-ray spectroscopy of atomically thin semiconductors
Anna Rupp, Jonas Göser, Zhijie Li +3
We report the implementation of energy dispersive X-ray spectroscopy for layered semiconductors in the form of atomically thin transition metal dichalcogenides. The technique is ba…
