Sentence examples for migration of vacancies from inspiring English sources

By applying a Gaussian relaxation model, the P desegregation during prolonged PIA at higher temperatures was found to be assisted by the formation and migration of vacancies.

The driving force of the relaxation process can be proposed as a dislocation dragging mechanism controlled by the migration of vacancies without break-away.

The achievement of equilibrium in this "upquenching" process depends, at least in part, upon the migration of vacancies from the surface into the interior of the solid.

The latter is characterized by rounded crystals (xenomorphous habit) bearing either a high density of dislocations or geometrical internal porosity linked to the migration of vacancies through the Kirkendall effect.

The diffusion combined with the drift of the oxygen vacancies under an applied negative bias could lead to accelerated migration of vacancies, resulting in higher slopes when transitioning from the HRS to LRS, as compared to the transition from LRS to HRS under positive sweeping.

Using ultrasonic shear waves, we study the kinetics of migration of vacancy to dislocations in aluminum.

Our results reveal that Re doping can inhibit the formation of Ni vacancies but facilitate the formation of Al vacancies, and can also inhibit the migration of neighboring vacancies.

The formation and migration energies of vacancies in copper are 1 eV and 0.8 eV, respectively (Hochrainer & El-Azab, 2015).

On the other hand, it is generally agreed that the conductive mechanism of the ZnO switching layer is attributed to the migration of oxygen vacancies because the formation energy of the oxygen vacancies is relatively lower than that of other intrinsic defects[17, 29 31].

It is also found that U and N vacancies have close migration energies, and O impurities accelerate migration of N vacancies nearby.

Switching mechanism is due to migration of oxygen vacancies under electric field.
