Point defect:

When the deviations or irregularities exist from the ideal arrangement around a point or an atom in a crystalline substance, the defect is called point defect.

 Line defect:

When the deviation from the ideal arrangement exists in the entire row of lattice points, the defect is called line defect.

 Dislocation:

Dislocations are  type of defect in crystals. Dislocations are areas where the atoms are out of position in the crystal structure. Dislocations are generated and move when a stress is applied.

 Planar defects:

Planar defects are interfaces between homogeneous regions of the material. Planar defects include grain boundaries, stacking faults and external surfaces.
