AbstractThe implantation of Ag into MgO (100) single crystals, followed by thermal annealing at 1100°C, leads to dramatic changes in their optical properties. The changes in the optical properties are due to the presence of small Ag clusters which are formed in the annealed samples. The small Ag clusters are obtained by thermal annealing of the implanted MgO crystals between 600°C and 1100°C to investigate the changes in cluster sizes and to correlate with changes in their optical properties. Sample characterization is carried out using optical spectrophotometry to confirm the effective presence of Ag clusters and Rutherford Backscattering Spectrometry (RBS) to study the profile of Ag clusters.

ABSTRACTBuried single-crystal YSi1.7 layers have been synthesized using high fluence implants of 330 keV yttrium ions into (111) Si held at 450°C followed by post-implant anneals of 1000°C . Rutherford backscattering spectrometry showed that an implant fluence of 3.6 X 1017 Y/cm2 forms a continuous layer of uniform thickness. Whereas, implant fluences of 1 — 2 x 1017 Y/cm2 form a thin continuous YSi1.7 layer with what are believed to be Y-silicide precipitates above and below the YSi1.7 layer. Strains resulting from the YSi1-7 layers were evaluated from x-ray rocking curves using a double crystal diffractometer.

In this study we investigated depth distributions of elements in the multilayer structures of TiO\(_2\)/SiO\(_2\)/Si before and after ion irradiation. The samples were implanted with Ne\(^+\), Ar\(^+\), Kr\(^+\) and Xe\(^+\) ions. For each implantation the multilayer structures were irradiated by the ions with the energy 100, 150, 200 and 250 keV. The elemental concentrations in the samples were analyzed by the Rutherford Backscattering Spectrometry (RBS) method. It was found that the transition layers existed between the TiO\(_2\) and SiO\(_2\) layers. Formation of these layers derived from the ion beam mixing that was occurred at TiO\(_2\)/SiO\(_2\) interface after irradiation process. The depth profiles show that thickness of the transition layers increased with the growing energy and atomic mass of the implanted ions.

AbstractRutherford backscattering spectrometry and channeling techniques have been used to investigate the crystalline quality and interfacial properties of epitaxially grown CeO2 and Ce0.7Zr0.3O2 films on yttria-stabilized ZrO2(111) substrates. Both films appear to have high crystalline quality with minimum yield of Ce in the CeO2and Ce0.7Zr0.3O2 films determined to be 4.7% and 12.1% respectively. Visibility of more Ce atoms to the ion beam at the interface compared to the bulk of the film indicates that both films show significant disorder at the interface. The normalized angular yield curves obtained from Ce and Zr indicate that the Ce atomic rows in the CeO2 film are parallel to the Zr atomic rows in the substrates. Approximately 88% of the Zr atoms substitutionally occupy the Ce cation lattice sites in the Ce0.7Zr0.3O2 film.

Cu/Al2O3 bilayer samples were produced by vapor deposition and irradiated successively with 150 keV Ar ions up to a dose of 500 dpa. Ion beam mixing effects were studied by 2 Me V He+ Rutherford backscattering spectroscopy (RBS). Concentration depth profiles show the mixing of Cu, Al, and O atoms in the sample. Because of the low mixing efficiency found in this study, Al2O3-dispersion strengthened Cu alloys seem to be good candidates as structural materials in fusion reactors.

ABSTRACTRutherford backscattering spectrometry (RBS) is used to characterize the stoichiometry of graphite intercalation compounds (GIC). Specific application is made to several stages of different donor and acceptor compounds and to commensurate and incommensurate intercalants. A deviation from the theoretical stoichiometry is measured for most of the compounds using this non-destructive method. Within experimental error, the RBS results agree with those obtained from analysis of the (00ℓ) x-ray diffractograms and weight uptake measurements on the same samples.

The analysis of material composition by ion-beam analysis (IBA) is becoming a standard method, similar to electron microscopy. A pool of IBA methods exists, from which the combination of particle-induced-X-ray emission (PIXE), particle induced gamma-ray analysis (PIGE), nuclear-reaction-analysis (NRA), and Rutherford-backscattering-spectrometry (RBS) provides the most complete analysis over the whole periodic table in a single measurement. Yet, for a highly resolved and accurate IBA analysis, a sophisticated technical setup is required integrating the detectors, beam optics, and sample arrangement. A new end-station developed and installed in Forschungszentrum Jülich provides these capabilities in combination with high sample throughput and result accuracy. Mechanical tolerances limit the device accuracy to 3% for RBS. Continuous pumping enables 5*10−8 mbar base pressure with vibration amplitudes < 0.1 µm. The beam optics achieves a demagnification of 24–34, suitable for µ-beam analysis. An in-vacuum manipulator enables scanning 50 × 50 mm² sample areas with 10 nm accuracy. The setup features the above-mentioned IBA detectors, enabling a broad range of analysis applications such as the operando analysis of batteries or the post-mortem analysis of plasma-exposed samples with up to 3000 discrete points per day. Custom apertures and energy resolutions down to 11 keV enable separation of Fe and Cr in RBS. This work presents the technical solutions together with the quantification of these challenges and their success in the form of a technical reference.
