Patent (populärvet., debatt m.m.)abstract
- ABSTRACT A device (1) and a method for fabricating such a device is described. The device (1) comprises a device layer (4), a substrate (2) defining a substrate plane (3). A device layer plane (5) is defined on the side of the device layer (4) facing the substrate (2). The device also comprises a waveguide (7) for guiding an electromagnetic wave. The waveguide (7) is supported on the substrate (2) via a support structure (6) extending from the substrate (2) to the device layer (4). The ratio of the largest distance (D1), perpendicular to the substrate plane (3), between a free surface of the waveguide (7) facing the substrate and any solid material to the height (h) of the waveguide (7) is more than 6, i.e. D1/h \textgreater 6. The ratio of the distance (D2), perpendicular to the substrate plane (3), between the device layer plane (5) and the substrate plane (3) to the height (h) of the waveguide (7) is more than 6, i.e. D2/h \textgreater 6.

Patent (övrigt vetenskapligt/konstnärligt)abstract
- TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The barrier layer consists of cerium dioxide. The barrier layer is endowed with yttrium, gadolinium, niobium or samarium. The barrier layer covers at least on one side of the ferritic component, as thin, preferably thick film. The barrier layer is not thicker than 10 mu m, preferably thinner than 2 mu m. The ferritic component is a porous metallic substrate and the nickel component is an anode. The ferritic component is an inter-connector and the nickel component is a nickel network. The barrier layer consists of: (calcium, strontium, barium)1-3x/2 (yttrium, lanthanide (ln))x titanium oxide (where Xy is 0-0.1 and/or Xln is 0-0.67); chromium oxide and/or chromium(II, III) oxide, manganese(II, III) oxide; iron(II) oxide and/or iron(II, III) oxide; cerium1-x-y (yttrium, lanthanide)x (titanium, niobium)yO2 (where x is 0-0.5 and y is 0-0.2); lanthanide1-x(strontium, calcium)x (magnesium oxide (mgO3)) aluminum oxide (AlO3), chromium oxide (CrO3) (where x is 0.1-0.5).
