Defect, or irregularity, within an ordered structure.
Notes:
- A screw dislocation is a structure in which a helical path is traced around a linear defect (dislocation line) by the atomic planes in the crystal lattice.
- An edge dislocation is a defect where an extra half-plane of atoms is introduced mid-way through the crystal.
- In the context of lithography, a dislocation may be found in a block copolymer pattern.
