Question
What do you mean by point defect in a crystal?
✓

Answer

Point defects are imperfections in the structure of a material at specific points within its lattice. These defects can arise due to missing atoms (vacancies), extra atoms (interstitials), or atoms occupying irregular positions (substitutional defects). They influence material's properties such as electrical conductivity and mechanical strength.
