The solid-liquid interface formed by single terminated muscovite mica in contact with two different ionic solutions is analyzed using surface X-ray diffraction. Specular and nonspecular crystal truncation rods of freshly cleaved mica immersed in CsCl or RbBr aqueous solution were measured. The half monolayer of the surface potassium ions present after the(More)
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)
Article history: Received 27 July 2015 Received in revised form 7 January 2016 Accepted 22 January 2016 Available online 26 January 2016 25 nm thick Gd-doped ceria thin films were grown on yttria-stabilized zirconia (YSZ) substrates with (110) and (111) orientation by pulsed laser deposition to study both their crystalline structure and interfacial(More)
We report an in situ surface X-ray diffraction study of liquid AuIn metal alloys in contact with zinc-blende InP (111)(B) substrates at elevated temperatures. We observe strong layering of the liquid metal alloy in the first three atomic layers in contact with the substrate. The first atomic layer of the alloy has a higher indium concentration than in bulk.(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
A sample chamber has been constructed for studying the growth of thin films by pulsed laser deposition in situ with surface X-ray diffraction. The achievable temperature ranges from room temperature to 1073 K in a controlled oxygen environment. The partial pressure of the oxygen background gas covers the range from 0.1 to 10(5) Pa. The first results,(More)
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)
The initial heteroepitaxial growth of YBa{2}Cu{3}O{7-delta} films on SrTiO3(001) substrates during pulsed laser deposition shows a growth-mode transition and a change of growth unit. The growth starts with two blocks, each two-thirds the size of the complete unit cell. The first of these blocks grows in a step-flow fashion, whereas the second grows in the(More)
