Here Qfr is the energy required for the formation of each Frenkel defect, and N is the
total number of lattice sites. (Also, as in previous discussions, k and T represent Boltzmann's
constant and the absolute temperature, respectively.) The factor 2 is present in the
denominator of the exponential because two defects (a missing cation and an interstitial
cation) are associated with each Frenkel defect.
Similarly, for Schottky defects, in an AX-type compound, the equilibrium number (Ns) is a
function of temperature as
N, = N exp
Qs
... (2)
Where Qs represents the Schottky defect energy of formation.
Example 1 Calculate the number of Schottky defects per cubic meter in potassium chloride at
500 °C The energy required to form each Schottky defect is 2.6 eV, while the density for KCI
(at 500 °C) is 1.955 g/cm³. Atomic…
