Abstract
The defect chemistry model is developed as a function of the nonmolecularity (ΔX) and nonstoichiometry (ΔY), and the formation energies of defects are also considered. In this model, the p-type conductivity can occur in the region withAX< 0 and Δ Y< 0 and n-type conductivity can occur in the region with Δ X> 0 and Δ Y> 0. For above given regions, itcould be possible to define a critical relation as ΔXC=8Δ Y/(1—2Δ Y). The p-type conductivity occurs in the AX (morenegative value) <ΔXC region at a constant Δ Y value. As the decreasing of AX negative value, the type conversion appears near the ΔX equals to ΔXC region, and then it was dominated by n-type conductivity.
