    Transition Metal Oxides
    Invited
    C. Bernhard Infrared ellipsometry studies of the electronic and structural properties of oxide-based heterostructures will be presented. As a first example, it is shown that this technique enables one to directly probe the mobility and the depth profile of the concentration of the confined electrons at the LaAlO3/SrTiO3 interface [1]. In addition, preliminary results on the electric field...

    Metal-Insulator Systems
    Invited
    Y. Matiks, P. Horsch, B. Keimer, and A. V. Boris Max Planck Institute for Solid State Research, Heisenbergstr. 1, DE-70569 Stuttgart, Germany Compounds composed of chains of edge sharing Cu2+O4 plaquettes have the peculiar property that the magnitude of the nearest-neighbor hopping matrix element along the chains is anomalously small due to the orthogonality of the 2pσ orbitals on oxygen...

  3. 146. How bad metals turn good: spectroscopic signatures.

    Metal-Insulator Systems
    Invited
    Antoine Georges College de France, Paris Many materials with strong electronic correlations display metallic-like resistivity up to very high temperature, with values exceeding the Ioffe-Regel-Mott (IRM) criterion. Yet, at low enough temperature, good metallic conductivity obeying Fermi liquid behaviour can be recovered. In this talk, I will explore how this crossover takes place. I will...
