Crystalline imperfections
WebBased on dimensionality, we can classify the crystal defects broadly into three major types. 1 2 3 . Zero dimensional (Point defect: Vacancy or interstitial) . One dimensional (Line defect: Dislocation) . Two dimensional (Surface Defect) Point Imperfection. Point imperfections are also referred to as zero-dimensional imperfections.
