Atomically thin materials such as graphene and monolayer transition metal dichalcogenides
(TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality …

Abstract Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as
MoS 2, WS 2, MoSe 2, and WSe 2, have received extensive attention in the past decade due …

Understanding and controlling disorder is key to nanotechnology and materials science.
Traditionally, disorder is attributed to local fluctuations of inherent material properties such …

Moiré superlattices in van der Waals heterostructures have emerged as a powerful tool for
engineering quantum phenomena. Here we report the observation of a correlated interlayer …

The optical selection rules for interband transitions in WSe 2, WS 2, and MoSe 2 transition
metal dichalcogenide monolayers are investigated by polarization-resolved …

The optical properties of transition metal dichalcogenide monolayers are widely dominated
by excitons, Coulomb-bound electron–hole pairs. These quasi-particles exhibit giant …

Monolayer transition metal dichalcogenides have strong Coulomb-mediated many-body
interactions. Theoretical studies have predicted the existence of numerous multi-particle …

Strong Coulomb interactions in single-layer transition metal dichalcogenides (TMDs) result
in the emergence of strongly bound excitons, trions, and biexcitons. These excitonic …

A panoply of unconventional electronic states has been observed in moiré superlattices.
Engineering similar bosonic phases remains, however, largely unexplored. We report the …

We report light emission around 1 eV (1240 nm) from heterostructures of MoS 2 and WSe 2
transition metal dichalcogenide monolayers. We identify its origin in an interlayer exciton …
