Web15 hours ago · Effect of local chemical environment on the point defects in AlNbTiZr refractory high entropy alloys WebAn example of this phenomenon, called a Frenkel defect A defect in an ionic lattice that occurs when one of the ions is in the wrong position., is a cation that occupies a tetrahedral hole rather than an octahedral hole in the anion lattice (part (b) in Figure 8.4.4). Frenkel defects are most common in salts that have a large anion and a ...

WebAug 17, 2024 · Additionally, charged nitrogen Frenkel pair was found to be a relatively stable defect complex and its well separation distance was about 3.9 Å. Part of our results are in good agreement with the experimental results, and our work provides underlying insights of the identification and dynamics of nitrogen interstitial in GaN material. WebConsequences of Frenkel defect: 1. The closeness of like charges tends to increase the dielectric constant of the crystal. 2. The crystal showing a frenkel defect conducts electricity to a small extent by ionic mechanism. 3. The density of the crystal remains the same.
