Abstract

Abstract : One‐dimensional (1D) atomically thin crystals have attracted considerable interest thanks to their novel properties which are different from the 2D sheet counterparts. For example, 1D MoS2 nanoribbons are metallic and exhibit unusual magnetic properties. In article no.1900063, Fangping Ouyang, Han Huang and co‐workers report on the synthesis of 1D MoS2 nanoribbons on sapphire(0001) supported monolayer MoS2 flakes without catalysts through an atmospheric pressure chemical vapor deposition approach. These nanoribbons grow along the ⟨10–10⟩ direction of the underlying flakes. The stacking modes between the nanoribbons and underlying flakes are either AB or AC due to residual strains. 1D MoO x S2− x crystals are treated as precursors, which transform to MoS2 nanoribbons through sulfurization. Such TMD nanoribbons have more edge terminations which indicate distinct physicochemical properties.
