ÉTYMOLOGIE DU MOT FRENKEL DEFECT
Named after I. I. Frenkel (1894–1952), Russian physicist.
QUE SIGNIFIE FRENKEL DEFECT EN ANGLAIS
Défaut Frenkel
Le défaut de Frenkel est un type de défaut des solides cristallins. Il consiste à déplacer un atome de sa position en treillis vers un site interstitiel, en créant une vacance sur le site d'origine et un défaut interstitiel au nouveau lieu.
définition de Frenkel defect dans le dictionnaire anglais
La définition du défaut de Frenkel dans le dictionnaire est un défaut cristallin dans lequel un ion de réseau s'est déplacé vers une position interstitielle laissant un site de réseau vacant.

Principles and Applications of Chemical Defects
In any crystal of formula MX, a Frenkel defect consists of one interstitial atom plus
one vacant site in the sub-lattice where that atom would normally be found.
Because we are simply moving ions around within the crystal we do not find that
we ...

7.2.4 Frenkel Defect In an ionic crystal, if a cation is removed from its regular site
and transferred to an interstitial site, then it is said to be Frenkel defect. Since the
crystal demands charge neutrality, the cation vacancy does not take place alone

Frenkel Defect : In this defect a vacancy or hole may exist in the lattice because
one ion occupies a position on the interstitial space rather than its appropriate
site in the lattice. Positive ions are smaller hence they are more likely to occupy ...
