The surface structure of Rh oxide
The surface and interface structure of the RhO2 ultra-thin film grown on Rh(100) has been investigated by means of x-ray photoelectron diffraction. Analysis of 2D angular distribution intensities of the O1s and Rh3d5/2 chemically shifted core levels allowed us to reveal a rippled buckling of the metal surface.

The surface and interface structure of the RhO2 ultrathin film grown on Rh(100) is investigated by means of x-ray photoelectron diffraction. Experimental and simulated one- and two-dimensional angular distribution intensities of the O1s and Rh3d5/2 chemically shifted core levels are quantitatively analyzed. The previously proposed O–Rh–O trilayer model is independently confirmed. A rippled buckling of the metal surface is observed at the oxide–metal interface, with a mean interfacial Rh–O distance which is 0.2 Å larger with respect to previous findings. The link between the local atomic rearrangement and the overall geometric and electronic properties of the oxide is discussed on |
the basis of a thorough comparison with the corresponding RhO2 rutile structure.
