Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

The design and control of material interfaces is a foundational approach to realize
technologically useful effects and engineer material properties. This is especially true for two …

Van der Waals (vdW) heterostructures based on transition metal dichalcogenides (TMDs)
generally possess a type-II band alignment that facilitates the formation of interlayer excitons …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

An exciton is the bosonic quasiparticle of electron–hole pairs bound by the Coulomb
interaction. Bose–Einstein condensation of this exciton state has long been the subject of …

Excitons (coupled electron–hole pairs) in semiconductors can form collective states that
sometimes exhibit spectacular nonlinear properties. Here, we show experimental evidence …

Heterostructures comprising different monolayer semiconductors provide an attractive
setting for fundamental science and device technologies, such as in the emerging field of …

Nonlinear interactions between excitons strongly coupled to light are key for accessing
quantum many-body phenomena in polariton systems. Atomically-thin two-dimensional …

Monolayer group-VI transition metal dichalcogenides have recently emerged as
semiconducting alternatives to graphene in which the true two-dimensionality is expected to …

We directly monitor exciton propagation in freestanding and SiO 2-supported WS 2
monolayers through spatially and time-resolved microphotoluminescence under ambient …
