A two-dimensional (2D) heterobilayer system consisting of MoS2 on WSe2, deposited on epitaxial graphene, is studied by scanning tunneling microscopy and spectroscopy at temperatures of 5 and 80 K. A moiré pattern is observed, arising from lattice mismatch of 3.7% between the MoS2 and WSe2. Significant energy shifts are observed in tunneling spectra observed at the maxima of the moiré corrugation, as compared with spectra obtained at corrugation minima, consistent with prior work. Furthermore… 
Observation of moiré excitons in WSe2/WS2 heterostructure superlattices
Moiré superlattice exciton states are observed in WSe2/WS2 heterostructures with closely aligned layers, described by a theoretical model in which the periodic moiré potential is much stronger than the exciton kinetic energy and generates multiple flat exciton minibands.
Mapping Modified Electronic Levels in the Moiré Patterns in MoS2/WSe2 Using Low-Loss EELS.
The effect of the twist angle in MoS2/WSe2 heterostructures is explored using high-resolution scanning transmission electron microscopy and electron energy-loss spectroscopy to observe weak interaction between the layers at higher twist angles and stronger interaction for lower twist angles.
Moiré Intralayer Excitons in a MoSe2/MoS2 Heterostructure.
The periodic in-plane potential results in a splitting of the MoSe2 exciton and trion in emission and (for the exciton) absorption spectra, and the observed energy difference between the split peaks is fully consistent with theoretical predictions.
Tuning Valleys and Wave Functions of van der Waals Heterostructures by Varying the Number of Layers: A First-Principles Study.
A simple and yet powerful way to tune band edges and the real-space extent of the electron and hole wave functions in TMDC heterostructures is suggested, potentially affecting strongly the lifetime and dynamics of interlayer excitons.
Intervalley Scattering of Interlayer Excitons in a MoS2/MoSe2/MoS2 Heterostructure in High Magnetic Field.
This work accounts for the nontrivial behavior of the valley polarization as a function of the magnetic field by considering the interplay between exchange interaction and phonon-mediated intervalley scattering in a system consisting of Zeeman-split energy levels.
Deep moiré potentials in twisted transition metal dichalcogenide bilayers
In twisted bilayers of semiconducting transition metal dichalcogenides (TMDs), a combination of structural rippling and electronic coupling gives rise to periodic moire potentials that can confine

Valley excitons: From monolayer semiconductors to moiré superlattices
Abstract Group-VIB transition metal dichalcogenides have recently emerged as a novel class of two-dimensional semiconductors. Monolayers feature direct bandgap in the visible range, with band-edges
Imaging moiré flat bands in three-dimensional reconstructed WSe2/WS2 superlattices
The results reveal that the strain redistribution and 3D buckling in TMD heterostructures dominate the effective moiré potential and the corresponding moirÉ flat bands at the Brillouin zone K points.
Epitaxial Synthesis of Monolayer PtSe2 Single Crystal on MoSe2 with Strong Interlayer Coupling.
This study opens a new way to synthesize uniform PtSe2 monolayers and other Pt-based heterostructures and shed considerable lights on optoelectronics in vdW solids consisting of weak and strong interlayer coupled materials.
