Frenkel Schottky defects

In a MO2 oxide (where M4+ is a tetravalent metal and O is Oxygen) there are three types of endogenous defects (i) Schottky defects with an equilibrium constant Ks, (ii) Frenkel cationic sublattice defects with equilibrium constant KCF; and (iii) anionic sublattice Frenkel defects with equilibrium constant KAF. D2O5 donor impurity (where D5+ is a pentavalent metal) is introduced into the material Construct the quantitive diagram according to the following:

log-log diagram of the concentrations of all the system defects as a function of the concentration of the dopant D2O5 impurity for constant receptor temperature taking into account that in MO2 oxide the dominant source of endogenous defects is the Frenkel anionic sublattice defects while Schottky defects coexist to a lesser extent.
