Abstract
Recent calculations on coincidence twist grain boundaries in oxides with the rocksalt structure have shown that the interfaces are only weakly bound. This is in contrast with experiment in which twist grain boundaries have been observed in MgO. The static lattice relaxation calculation presented here predicts a restructured stable [001] twist boundary in NiO. The results are equally applicable to the other oxides with the same structure.
