Polarity governs atomic interaction through two-dimensional materials

Transparency of two-dimensional (2D) materials to inter-molecular interactions has been an unresolved problem. Previous researchers found that water droplets interact with underlying substrates through graphene, as if the graphene is "transparent". However, graphene's transparency determined by droplet wetting angles has been controversial. Recently, precise atomic alignment between epitaxial films and substrates through monolayer graphene has been discovered in a GaAs/graphene/GaAs structure. This finding experimentally confirms the existence of remote atomic interaction through graphene. However, the mechanism of remote interaction through 2D materials at atomic-scale and its relationship with the bonding chemistry of 2D materials have not been fully understood.
