This paper reports experimental evidence for an incipient epitaxial growth of vanadium oxide at the TiO2(110) surface. This finding is based on a x-ray photoelectron diffraction and low-energy electron diffraction study of a submonolayer of vanadium deposited at the TiO2(110) surface, performed after annealing at 473 K in ultrahigh vacuum conditions. The data unambiguously show that vanadium atoms occupy selected sixfold-coordinated titanium sites which underbridge oxygen atoms of the topmost layer and that the TiO2(110) long-range surface structural order is preserved.

Abstract
This paper reports experimental evidence for an incipient epitaxial growth of vanadium oxide at the TiO2(110) surface. This finding is based on a x-ray photoelectron diffraction and low-energy electron diffraction study of a submonolayer of vanadium deposited at the TiO2(110) surface, performed after annealing at 473 K in ultrahigh vacuum conditions. The data unambiguously show that vanadium atoms occupy selected sixfold-coordinated titanium sites which underbridge oxygen atoms of the topmost layer and that the TiO2(110) long-range surface structural order is preserved.
