Question

The two dimensional defects that separate two regions of a crystal is called as_________
Schottky defect
line defect
surface defect
volume defect
point defect​

Answer 1

A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. ... In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated
