    • note
    • Our calculations show that the energy of the corundum-type structure is too high compared with the ferroelectric structure by about 3 eV, and thus cannot be the paraelectric phase. In contrast, the centrosymmetric perovskite-type (R3̄c) structure gives a very reasonable energy difference, and is therefore adopted in our analysis.
