【 摘 要 】

This paper describes a 3 x 1 surface reconstruction on the LAO (110) surface and its atomic structure analyzed from experimental electron diffraction data coupled with X-ray photoelectron spectroscopy analysis and reinforced by density functional theory calculations. We construct the multidimensional convex hull for the system with excess Al2O3 and in the presence of water. All the evidence points towards the reconstruction being very similar to the 3 x 1 reconstruction on the SrTiO3 (110) surface with two hydrogen atoms added for valence neutrality.
