Description:
Article Although screw dislocations impact on the properties of various engineering materials, their investigation on the atomic scale has been challenging. Here, the authors use optical sectioning in a scanning transmission electron microscope to achieve direct imaging of screw displacements around a screw dislocation core in GaN.
