Defects play vital roles in tailoring structures and properties of materials including the atomically thin two-dimensional(2D)materials,and increasing demands are requested to find effective ways to realize the defect engineering,i.e.,tuning the defects and thus the materials’structure–property in a well-controlled way.Herein,we propose a novel method to tune the structures and configurations of one-dimensional(1D)line defects in monolayer MoS2 via mass transport induced structural transformation.By using atomic-resolved annular dark-field scanning transmission electron microscopy(ADF-STEM),we demonstrate in situ that sulfur vacancy line defect can be healed locally into defect-free MoS_(2)lattice via the desorption of Mo atoms from vacancy lines and adsorption into a moving Mo cluster.Furthermore,directional transport of Mo atoms(or Mo cluster)along the sulfur vacancy lines can induce the formation of Mo chains.Such a mass transport induced defect tuning provides more operational routes for the rational defect designing and property tuning in MoS_(2)as well as other related 2D materials. 展开更多
