Atomic-scale mapping of hydrophobic layers on graphene and few-layer MoS2 and WSe2 in water

Abstract

Interfacial water plays a crucial role in mediating hydrophobic interactions. Here, the authors directly image the interfacial water organization in graphene, few-layer MoS2 and WSe2 through 3D-AFM technique to unveil that the distance between adjacent layers is about 0.30 nm larger than theoretically predicted values.
