  • Publication number: 20230170426
    Abstract: The present disclosure relates to transparent conducting films (TCF). In particular, the disclosed TCF are transparent to ultraviolet (UV) light. The TCF can be grown by radio frequency (RF) sputtering and remain in the advantageous perovskite phase. Optical stacks made of substrates with deposited TCF are also disclosed.

  • Publication number: 20220246714
    Abstract: The present disclosure provides a layering structure that permits integration of epitaxially oriented perovskite oxides, such as bismuth ferrite (BiFeO3), epitaxially oriented barium titanate (BaTiO3), epitaxially oriented (SrTiO3), or their superstructures (BTO/STO) or solid solutions, onto a Si substrate through a perovskite buffer layer. The structure can retain thermal process-sensitive dopant positions and other thermal process window-sensitive features through atomic layer deposition of an oxide perovskite. Also provided are methods of preparing these layered structures.

  • Publication number: 20180141162
    Abstract: A method for manufacturing a mechanical component. The method comprises the application of an additive manufacturing method, wherein the method comprises the deposition of a powder material and local melting and resolidification of the powder material, thereby providing a solid body. The method furthermore comprises the selective provision of a powder material in which the lattice parameter of the gamma prime phase is larger than the lattice parameter of the gamma phase at least in a part of a temperature range from equal to or larger than 0° C. and equal to or lower the gamma prime solvus temperature.
