  • Patent number: 11555242
    Abstract: Methods are provided herein for forming transition metal oxide thin films, preferably Group IVB metal oxide thin films, by atomic layer deposition. The metal oxide thin films can be deposited at high temperatures using metalorganic reactants. Metalorganic reactants comprising two ligands, at least one of which is a cycloheptatriene or cycloheptatrienyl (CHT) ligand are used in some embodiments. The metal oxide thin films can be used, for example, as dielectric oxides in transistors, flash devices, capacitors, integrated circuits, and other semiconductor applications.

  • Patent number: 9878516
    Abstract: A metamaterial thin film with plasmonic properties formed by depositing metallic films by atomic layer deposition onto a substrate to form a naturally occurring mosaic-like nanostructure having two-dimensional features with air gaps between the two-dimensional features. Due to the unique deposition nanostructure, plasmonic thin films of metal or highly conducting materials can be produced on any substrate, including fabrics and biological materials. In addition, these plasmonic materials can be used in conjunction with geometric patterns that may be used to create multiple resonance plasmonic metamaterials.

  • Publication number: 20160333476
    Abstract: The invention provides an improved method for producing cathode diffusion barrier layer, and a SOFC with high efficiency and longevity. It comprises depositing a pure ceria or aliovalently doped ceria layer, by ALD, on the electrolyte layer of the sintered half cell. The surface of a electrolyte onto which film is to be deposited is exposed to a dose of vapor from one or more lanthanide first precursors. Any excess of unreacted vapor from that precursor is removed. Next, a vapor dose of the second precursor is brought to the surface and allowed to react. A second purge completes the ALD cycle, which is repeated to build up thicker films. This ceria layer forms a cathode diffusion barrier layer on top of which a cobaltite based cathode layer is applied by screenprinting, and the cathode diffusion barrier layer and cathode layer are heated together to form a SOFC.

  • Patent number: 7498272
    Abstract: The present invention concerns a process for depositing rare earth oxide thin films, especially yttrium, lanthanum and gadolinium oxide thin films by an ALD process, according to which invention the source chemicals are cyclopentadienyl compounds or rare earth metals, especially those of yttrium, lanthanum and gadolinium. Suitable deposition temperatures for yttrium oxide are between 200 and 400° C. when the deposition pressure is between 1 and 50 mbar. Most suitable deposition temperatures for lanthanum oxide are between 160 and 165° C. when the deposition pressure is between 1 and 50 mbar.
