The equations for the concentration of the three point defects contain in parts the differnce of the formation enthalpies of Schottky or Frenkel defects. | ||
Calculate the ratio of the concentration of Schottky to Frenkel defects as a function of this enthalpy difference. | ||
Discuss the result. Show in in particular, how large the difference must be if 90% or 99%, resp., of the defects are to be of one kind. | ||
