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

Van der Waals heterostructures are synthetic quantum materials composed of stacks of
atomically thin two-dimensional (2D) layers. Because the electrons in the atomically thin 2D …

The growth of wafer-scale single-crystal two-dimensional transition metal dichalcogenides
(TMDs) on insulating substrates is critically important for a variety of high-end applications …

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 …

Interactions between quasiparticles are of fundamental importance and ultimately determine
the macroscopic properties of quantum matter. A famous example is the phenomenon of …

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 …

Charged excitons, or X±trions, in monolayer transition-metal dichalcogenides have binding
energies of several tens of meV. Together with the neutral exciton X 0 they dominate the …

Higher-order correlated excitonic states arise from the mutual interactions of excitons, which
generally requires a significant exciton density and therefore high excitation levels. Here, we …
