  Two-dimensional (2D) layered materials hosting dislocations have attracted
considerable research attention in recent years. In particular, screw
dislocations can result in a spiral topology and an interlayer twist in the
layered materials, significantly impacting the stacking order and symmetry of
the layers. Moreover, the dislocations with large strain and heavily distorted
atomic registry can result in a local modification of the structures around the
dislocation. The dislocations thus provide a useful route to engineering
optical, electrical, thermal, mechanical and catalytic properties of the 2D
layered materials, which show great potential to bring new functionalities.
This article presents a comprehensive review of the experimental and
theoretical progress on the growth and properties of the dislocated 2D layered
materials. It also offers an outlook on the future works in this promising
research field.
