    Crystal defects During crystal growth defects in the ideal crystal lattice can occur. They are characterized as zero-, one-, or two-dimensional. A vacancy or an interstitial atom is a zero-dimensional defect due to a missing atom on a lattice place or an additional atom on an interstitial (Figure 1.11).
