A mismatch of atomic registries between single-layer transition metal dichalcogenides (TMDs) in a two-dimensional (2D) van der Waals heterostructure produces a moiré superlattice with a periodic potential, which can be fine-tuned by introducing a twist angle between the materials. This approach is promising both for controlling the interactions between the TMDs and for engineering their electronic band structures, yet direct observation of the changes to the electronic structure introduced with…

Direct observation of minibands in a twisted graphene/WS2 bilayer

A new x-ray capillary technology for performing microfocused angle-resolved photoemission spectroscopy with a spatial resolution of ~1 μm is introduced, and the first direct observation of minibands in the electronic structure of a twisted heterobilayer is shown using microfocused ARPES.

Determination of band alignment in the single-layer MoS2/WSe2 heterojunction

The determination of band offsets in the heterostructure of transition metal dichalcogenides by using microbeam X-ray photoelectron spectroscopy and scanning tunnelling microscopy/spectroscopy shows that the electronic structures of WSe2 and MoS2 are well retained in their respective layers due to a weak interlayer coupling.

Resonantly hybridized excitons in moiré superlattices in van der Waals heterostructures

It is demonstrated that excitonic bands in MoSe2/WS2 heterostructures can hybridize, resulting in a resonant enhancement of moiré superlattice effects, which underpin strategies for band-structure engineering in semiconductor devices based on van der Waals heterostructure.

Determination of band offsets, hybridization, and exciton binding in 2D semiconductor heterostructures

The key unknown parameters in MoSe2/WSe2 heterobilayers are determined by using rational device design and submicrometer angle-resolved photoemission spectroscopy (μ-ARPES) in combination with photoluminescence and the spectrum of a rotationally aligned heterobilayer reflects a mixture of commensurate and incommensurate domains.

Direct Measurement of the Tunable Electronic Structure of Bilayer MoS2 by Interlayer Twist.

The electronic structure measurements reported here, including the evolution of the effective mass with twist-angle, provide new insight into the physics of twisted transition-metal dichalcogenide bilayers and serve as a guide for the practical design of MoS2 optoelectronic and spin-/valley-tronic devices.

Interlayer Excitons and Band Alignment in MoS2/hBN/WSe2 van der Waals Heterostructures.

A general first-principles method is presented to compute the electronic quasi-particle (QP) band structure and excitonic binding energies of incommensurate vdWHs and demonstrates the crucial role of self-energy and electron-hole interaction effects.

Interlayer Coupling in Twisted WSe2/WS2 Bilayer Heterostructures Revealed by Optical Spectroscopy.

The interlayer coupling for the WSe2/WS2 bilayer heterojunctions indicated by substantial PL quenching, enhanced absorption, and rapid charge transfer was found to be insensitive to the relative twist angle, indicating that stamping provides a robust approach to realize reliable optoelectronics.

Correlated insulator behaviour at half-filling in magic-angle graphene superlattices

It is shown experimentally that when this angle is close to the ‘magic’ angle the electronic band structure near zero Fermi energy becomes flat, owing to strong interlayer coupling, and these flat bands exhibit insulating states at half-filling, which are not expected in the absence of correlations between electrons.

Interlayer hybridization and moiré superlattice minibands for electrons and excitons in heterobilayers of transition-metal dichalcogenides

Geometrical moire patterns, generic for almost aligned bilayers of two-dimensional (2D) crystals with similar lattice structure but slightly different lattice constants, lead to zone folding and

Flat bands in twisted bilayer transition metal dichalcogenides

The crystal structure of a material creates a periodic potential that electrons move through giving rise to its electronic band structure. When two-dimensional materials are stacked, the resulting
