 Computations for various ABO3 parafskites were performed on their 001, 111, and 011 surfaces, revealing that the surface rumbling ass is larger on aoterminated surfaces than BO2 terminated ones. However, the surface energies are practically identical for both terminations. The computed bulk biochemical bond covalency increases near neutral and polar surfaces.
