Density functional theory modeling: Oxygen subsurface adsorption at the boundary formed by parallel missing-row domains with half unit-cell mismatch (a) results in the formation of two corner-sharing Cu2O tetrahedrons with the Cu2O(111)//Cu(100) (b) and a Cu2O tetrahedron with Cu2O(100)//Cu(100) (c) (red balls: oxygen atoms; blue balls: Cu atoms).
