Complexes can form between different kinds of point defects.

Such a film is more robust against point defects and can be made thicker to hold larger numbers of electrons.

The nitrogen-vacancy center is a point defect in the diamond lattice.

Appreciating the implications of point defect theory, his own ideas fell into a coherent pattern.

Grain boundaries also cause deformation in that they are sources and sinks of point defects.

The initial damaging events leading to the creation of point defects are generally complete in times of order 10−11 s.

This can be extended to find the equilibrium concentration of other types of surface point defects as well.

All of these point defects can be generated via thermal vibrations and have an equilibrium concentration.

In crystallography, a vacancy is a type of point defect in a crystal.

There are three main point defects.

Oxides exhibit an abundance of point defect sites.

It is the simplest point defect.

Thus damage to the crystal is visible, and point defects (interstitials) can even be distinguished from dislocations.

Point defects are defects that occur only at or around a single lattice point.

These irregularities are point defects and line defects.

Each individual ion produces many point defects in the target crystal on impact such as vacancies and interstitials.

In rocksalt surfaces, oxygen and metal cation vacancies are the most common point defects.

To this end, we have developped a 3-D model that describes the propagation of ultrasonic waves and their interaction with a point defect.

The theoretical description rests on a coupling of the point defects with the microstructure by nonlinear reactions.

Both these sets of data had been interpreted as indicating small defect clusters rather than a random distribution of point defects.

Figure 1 illustrates the names for the atomic positions and point defects on a surface for a simple cubic lattice.

Finally, as this point defect grows, the components of the two bilayers mix and diffuse away from the site of contact.

Point defects can nucleate reversed domains in ferromagnets and dramatically affect their coercivity.

Charged impurity ions and point defects have scattering cross-sections that are much greater than their neutral counterparts.

Some sites of atoms in the crystal lattice can be occupied by point defects, such as "alien" particles or vacancies.
