Akhildev V P

Described about continuation of point defects that is impurity type defects, it is two types, a) substitutional impurity and b) interstitial impurity. Also discussed about various one dimensional defects or line defects, and described about it's types. Edge dislocation and Screw dislocation are two types of line defects. If one extra half plane is added to the crystal or missed it is called edge dislocation type defect and if the structure of Crystal is slipped or or moved due to shear or something Screw dislocation occurs. Also solidification process, deformation etc are the sources of dislocation.
