ABSTRACT
The native defect structure of such oxides involves excess cations at interstitial positions of the oxide lattice with excess electrons in its conduction band. As discussed earlier, this may be represented by the following defect formation equilibrium:
(6.1)
for which one can write the following equilibrium constant at a constant temperature, T:
K(T) = [Zni] nZJ>b~ (6.2) where [Zni] and n represent the concentrations of interstitial zinc ions and excess electrons per m3 of ZnO lattice.
