This Letter reports an X-ray photoelectron diffraction study of similar to 5 V monolayers deposited by electron beam evaporation at the TiO2,(110) surface. Data clearly show that V grows as islands with a bcc structure having the [100] direction normal to the substrate surface. A detailed analysis of the V''2p and Ti''3p azimuthal curves indicates also an alignment of the [001] overlayer azimuth with the [(1) over bar 10] direction of the TiO2 substrate. These results are consistent with an epitaxial growth of bcc V at the TiO2(110) surface where a double V surface unit cell is matched to the TiO2(110) rectangular cell.
