ABSTRACTCo85Cr15-xTax(x:0, 2at%)/Cr films with microscopically flat surface were investigated for high density recording media. These films were deposited on silicon wafer and glass substrates at the substrate temperature Ts of 350 °C at argon pressure as low as sub-mTorr by using Facing Targets Sputtering (FTS) apparatus. The elevating of Ts promoted the Cr(200) orientation in film plane, leading to the in-plane c-axis orientation of Co crystallites. Addition of some elements such as Si, Ge and Ta in Cr thin film was found to stabilize Cr(110) crystal orientation even at Ts of 300 °C.

In this study, MgxZn1-xO thin film with x varied from 0 to 0.3 was deposited on silicon with the orientation of [1 0 0] using the sol-gel method and spin coating technique. The thin film was annealed at 550°C before being used as a template to grow vertically aligned carbon nanotubes (VACNTs). Field emission scanning electron microscopy (FESEM) indicates that the top view of VACNTs’ topography are very similar to the topography of the template used, MgxZn1-xO thin film. When the value of x increased, the grain size of the template becomes larger and rougher, which were also true with the VACNTs. The electrical properties were measured using IV measurement system, which indicates that the conductivity of the VACNTs is directly proportional to the grain size of the template. Raman spectroscopy was used to inspect the crystal orientation.

Set Up

A multipurpose six-axis κ-diffractometer, together with the brilliance of the ESRF light source and a CCD area detector, has been explored for studying epitaxial relations and crystallinity in thin film systems. The geometrical flexibility of the six-axis goniometer allows measurement of a large volume in reciprocal space, providing an in-depth understanding of sample crystal relationships. By a set of examples of LaAlO3thin films deposited by the atomic layer deposition technique, the possibilities of the set-up are presented. A fast panoramic scan provides determination of the crystal orientation matrices, prior to more thorough inspection of single Bragg nodes. Such information, in addition to a broadening analysis of families of single reflections, is shown to correlate well with the crystallinity, crystallite size, strain and epitaxial relationships in the thin films. The proposed set-up offers fast and easy sample mounting and alignment, along with crucial information on key features of the thin film structures.

Modification of the garnet-type solid electrolyte with a 10 nm Sn thin-film improves the contact and wetting performance between the garnet and the lithium metal and, thus enables fast and reversible lithium transport across their interface by forming a self-limited, conductive Li–Sn intermediate layer.

AbstractLanthanum-modified lead-titanate (Pbo.85Lao.1Ti03) thin films were fabricated by rf magnetron sputtering on various kinds of substrates such as single-crystal MgO (100), r-plane sapphire and SI (100) with an MgO thin film layer. All the films were able to be evaluated using nickel alloy electrodes which possess low reactivity with PbO, excellent heat-resistance and oxidation-resistance. The quality of these films was affected by the kind of substrate and crystal orientation of nickel alloy electrode used. Furthermore, by controlling the crystal orientation of the alloy electrode, films on Si (100) with an MgO (100) layer showed good ferroelectricity.

Lithium manganese oxide (LiMn2O4) had been a promising material for lithium-ion and thin film batteries. However, the LiMn2O4 had some problems such as the manganese dissolution into liquid electrolyte. In order to improve cycleability, we introduced SnOx layer as protective layer. This layer was deposited on spinel LiMn2O4 by using radio frequency magnetron sputtering. The deposited SnOx layer fully covered the LiMn2O4 , and didn’t make a change the crystallinity of the spinel films. The SnOx layer prevented direct contact of liquid electrolyte and improved the cycle retention.
