Point defects are defects that occur only at or around a single lattice point. They are not extended in space in any dimension. Strict limits for how small a point defect is are generally not defined explicitly. However, these defects typically involve at most a few extra or missing atoms. Larger defects in an ordered structure are usually considered dislocation loops. For historical reasons, many … WebThe various point defects are discussed below: 1. Vacancy: A vacancy is the simplest point defect and involves a missing atom within a metal. These detects may come up as a result of imperfect packing during the original crystallisation. They may also arise from thermal vibrations of the atoms at high temperatures. 2. Schottky Imperfections:
