hi, sure. Righ ordered arrangements of lattice defects have selective
catalytic properties. Actually, the word "defect" against perfection
of crystals may give negative sense, as the word "friction" in
mechanics! But without friction we cant walk, drive, etc. Here we see
the same situaton.These words also are relatively! when the
concentration of hole atoms in crystal is more,we say its hole
crystal, while it is ignorable, we have not hole crystal, although it
doesnt mean the number of hole atoms in the crystal is zero.
