Imaging lattice reconstruction in homobilayers and heterobilayers of transition metal dichalcogenides
Anna Rupp, Jonas Göser, Zhijie Li +3
Moiré interference effects have profound impact on the optoelectronic properties of vertical van der Waals structures. Here we establish secondary electron imaging in a scanning el…
Field-induced hybridization of moiré excitons in MoSe/WS heterobilayers
Borislav Polovnikov, Johannes Scherzer, Subhradeep Misra +10
We study experimentally and theoretically the hybridization among intralayer and interlayer moiré excitons in a MoSe/WS heterostructure with antiparallel alignment. Using a…
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…
Stacking-dependent exciton multiplicity in WSe bilayers
Zhijie Li, Jonathan Förste, Kenji Watanabe +6
Twisted layers of atomically thin two-dimensional materials realize a broad range of novel quantum materials with engineered optical and transport phenomena arising from spin and v…
Second- and third-order optical susceptibilities in bidimensional semiconductors near excitons states
Lucas Lafeta, Aurea Corradi, Tianyi Zhang +6
Semiconducting Transition Metal Dichalcogenides (TMDs) have significant nonlinear optical effects. In this work we have used second-harmonic generation (SHG) and the four-wave mixi…
Nonlinear dark-field imaging of 1D defects in monolayer dichalcogenides
Bruno R. Carvalho, Yuanxi Wang, Kazunori Fujisawa +10
Extended defects with one dimensionality smaller than that of the host, such as 2D grain boundaries in 3D materials or 1D grain boundaries in 2D materials, can be particularly dama…
Polariton hyperspectral imaging of two-dimensional semiconductor crystals
Christian Gebhardt, Michael Förg, Hisato Yamaguchi +8
Atomically thin crystals of transition metal dichalcogenides (TMDs) host excitons with strong binding energies and sizable light-matter interactions. Coupled to optical cavities, m…
Direct and Scalable Chemical Vapor Deposition of Ultrathin Low-Noise MoS2 Membranes on Apertures
Pradeep Waduge, Ismail Bilgin, Joseph Larkin +6
We show that atomically thin molybdenum disulfide (MoS2) crystals can grow without any underlying substrates into free-standing atomically-thin layers, maintaining their planar 2D…
Chemical Vapor Deposition Synthesized Atomically Thin Molybdenum Disulfide with Optoelectronic-Grade Crystalline Quality
Ismail Bilgin, Fangze Liu, Anthony Vargas +8
The ability to synthesize high-quality samples over large areas and at low cost is one of the biggest challenges during the developmental stage of any novel material. While chemica…
