WitrynaThe Frenkel type, the Schottky type, and the impurity type are all examples of point defects. The Frenkel defect occurs when a single ion is displaced from its typical lattice location and moves to a nearby interstice, or space between lattice atoms. Two ions of opposing sign escape the lattice in the Schottky defect. WitrynaOnce point defects start diffusing within the solid, they can interact with each other and form extended defects (linear, planar, or three-dimensional defects) so as to reduce the total energy. The following extended defects must be considered: • Dislocation-type defects: In general, dislocation-type defects are loops which can exhibit edge, …
