Atomistic simulation of SrTiO3 and BaTiO3 (110) surface relaxations
The (110) surface relaxations were calculated for SrTiO3 and BaTiO3 perovskites in a cubic phase. Using a shell model, the positions of atoms in 16 near- surface layers placed atop a slab of rigid ions are calculated. The strong surface rumpling and induced surface dipole moments perpendicular to the surface are predicted for both the O-terminated and TiO-terminated surfaces.
