摘要
The dc electrical conductivity of MgO-doped Cr//2O//3 and the defect models with the defect structure of a sesquioxide were investigated as a function of oxygen partial pressure, temperature, and dopant content. The electrical conductivity of MgO-doped Cr//2O//3 is increased with oxygen partial pressure and temperature. The electrical conductivity of MgO-doped Cr//2O//3 within the solubility limit is increased with MgO content because of the creation of holes and the annihilation of chromium vacancies.
