Reversible and selective ion intercalation through the top surface of few-layer MoS₂, Published online: 11 December 2018; doi:10.1038/s41467-018-07710-z

Electrochemical ion intercalation in 2D layered materials is known to occur through the material's edges, accompanied by frequent structural deformations. Here the authors show that in MoS2 flakes where the edges have been sealed, a reversible and ion-selective intercalation occurs through the top surface via the intrinsic defects.
