Probing the Interlayer Exciton Physics in a MoS2/MoSe2/MoS2 van der Waals Heterostructure

Andras Kis, Dumitru Dumcenco, Yen-Cheng Kung, Alessandro Surrente

Stacking atomic monolayers of semiconducting transition metal dichalcogenides (TMDs) has emerged as an effective way to engineer their properties. In principle, the staggered band alignment of TMD heterostructures should result in the formation of interlay ...

Fast diffusion of water nanodroplets on graphene

Gabriel Aeppli, Gabriele Tocci, Ming Ma

Diffusion across surfaces generally involves motion on a vibrating but otherwise stationary substrate. Here, using molecular dynamics, we show that a layered material such as graphene opens up a new mechanism for surface diffusion whereby adsorbates are ca ...
