Our anomalous surface x-ray diffraction study of the interface between SrTiO 3 (001) substrates and thin polar films of LaAlO 3 shows La/Sr interdiffusion leading to neutrally charged Sr 1−1.5x La x O layers. From a thickness of two unit cells, the LaAlO 3 film's interior retains its polar stacking sequence, which is compensated by a cationic compositional(More)
The supplementary material summarizes the following complementary fit results: from an area on the surface several mm away from the LSC electrode for three different conditions and for the UHV prepared clean YSZ (100) surface (see Table 1). In Figure 1 the corresponding occupancy profiles are shown. Figure 2 and 3 show the corresponding experimental data 1
Nickel nanoparticles supported by the yttria-stabilized zirconia (111) surface show several preferential epitaxial relationships, as revealed by in situ X-ray diffraction. The two main nanoparticle orientations are found to have their [111] direction parallel to the substrate surface normal and ∼41.3 degrees tilted from this direction. The former(More)
