ABSTRACTStable SBT sols for FRAM application were made from Sr-isopropoxide, Bi-acetate, and Ta-ethoxide with 2-ethoxyethanol as a solvent and chelating agent, TEA. The sol were spin-on coated on the Pt /Ti/SiO2/Si substrate. From the IR and DTA/TGA, the 2-ethoxyethanol -triethanolamine sol system is quite stable against aging. 5% excess Bi added sol and 800°C heat treatment of the thin film revealed the most crystallinity. There is a change in the orientation of thin film above 800°C heat treatment from c-axis to(105). The average grain size of thin film is very small, i.e., 40 nm at 800°C, and it has very narrow distributions, and the thickness of the coating were about 100nm, which would promise smaller electrode area and higher yield.

There is great interest in the growth of thin superconducting films of YBa2Cu3Ox on silicon, since this is a necessary first step in the use of this superconductor in a variety of possible electronic applications including interconnects and hybrid semiconductor/superconductor devices. However, initial experiments in this area showed that drastic interdiffusion of Si into the superconductor occurred during annealing if the Y-Ba-Cu-O was deposited direcdy on Si or SiO2, and this interdiffusion destroyed the superconducting properties. This paper describes the results of the use of a zirconia buffer layer as a diffusion barrier in the growth of thin YBa2Cu3Ox films on Si. A more complete description of the growth and characterization of these films will be published elsewhere.Thin film deposition was carried out by sequential electron beam evaporation in vacuum onto clean or oxidized single crystal Si wafers. The first layer evaporated was 0.4 μm of zirconia.

Cermets are designed to optimize the mechanical properties of ceramics (hard and strong component) and metals (ductile and tough component) into one system. However, the processing of such systems is a problem in obtaining fully dense composite without deleterious reaction products. In the lightweight (2.65 g/cc) B4C-Al cermet, many of the processing problems have been circumvented. It is now possible to process fully dense B4C-Al cermet with tailored microstructures and achieve unique combination of mechanical properties (fracture strength of over 600 MPa and fracture toughness of 12 MPa-m1/2). In this paper, microstructure and fractography of B4C-Al cermets, tested under dynamic and static loading conditions, are described.The cermet is prepared by infiltration of Al at 1150°C into partially sintered B4C compact under vacuum to full density. Fracture surface replicas were prepared by using cellulose acetate and thin-film carbon deposition. Samples were observed with a Philips 3000 at 100 kV.
