PPT-Crystal Imperfection

Crystals Basis with infinite space lattice Infinite periodicity Real crystals are finite in extent Therefore they have surface at boundary where some atomic bonds are broken Surface itself is an imperfection.

An ideal crystal can be described in terms a three-dimensionally periodic arrangement of points called lattice and an atom or group of atoms associated with each lattice point called motif:. 1 A perfect crystal, with every atom of the same type in the correct position, does not exist .
