Yttria and Ceria Doped Zirconia Thin Films Grown by Pulsed Laser Deposition
The Yttria stabilized Zirconia (YSZ) is a standard electrolyte for solid oxide fuel cells (SOFCs), which are potential candidates for next generation portable and mobile power sources. YSZ electrolyte thin films having a cubic single phase allow reducing the SOFC operating temperature without diminishing the electrochemical power density. Films of 8 mol% Yttria stabilized Zirconia (8YSZ) and fi...
متن کاملTensile Lattice Distortion Does Not Significantly Affect Oxygen Transport in Yttria-stabilized Zirconia (YSZ)– CeO2 Hetero-Interfaces
Biaxially-textured epitaxial thin-film hetero-structures of ceria and 8 mol% yttria-stabilized zirconia (8YSZ) were grown using Pulsed Laser Deposition (PLD) with the aim to unravel the effect of the interfacial conductivity on the charge transport properties. Five different samples were fabricated keeping the total thickness constant (300 nm) but with a different number of hetero-interfaces (b...
متن کاملInvestigation of the mechanical properties of various yttria stabilized zirconia based thin films prepared by aqueous tape casting
In this study various yttria doped zirconia based thin films were prepared by the aqueous tape casting method. The rheological property of the paste was studies. The phase content and microstructure of the samples was investigated by X-ray diffraction and scanning electron microscope, respectively. The mechanical properties of thin films were studied by Vickers microhardness and nanoindentatio...
متن کاملMagnetism in hafnium dioxide
Thin films of HfO2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia, or silicon substrates show ferromagnetic magnetization curves with little hysteresis and extrapolated Curie temperatures far in excess of 400 K. The moment does not scale with film thickness, but in terms of substrate area it is typically in the range 150–400 B nm −2. The magnetization exhibits a rem...
متن کاملLaser-assisted plasma coating at atmospheric pressure: production of yttria-stabilized zirconia thermal barriers
A laser-assisted plasma-coating technique at atmospheric pressure (LAPCAP) has been investigated. The electron temperature, electron density and gas temperature of the atmospheric-pressure plasma have been measured using optical emission spectroscopy (OES). LAPCAP utilizes laser ablation of 3 mol% yttria-stabilized zirconia into an atmospheric helium/nitrogen plasma to deposit thermal barrier c...
