  • Publication number: 20220018993
    Abstract: In an embodiment a layer system includes an effective refractive index profile extending between a substrate-side surface and an interface with an ambient medium, wherein an effective refractive index of the layer system decreases on average from the substrate-side surface in a direction of the interface with the ambient medium, wherein the effective refractive index profile has at least two local minima, and wherein a local minimum closest to the interface with the ambient medium is spaced from the interface.

  • Patent number: 9939556
    Abstract: A method for producing a reflection-reducing layer system on a substrate and a reflection-reducing layer system are disclosed. According to an embodiment the method includes depositing a refractive index gradient layer on the substrate by co-evaporation of an inorganic material and an organic material, wherein the refractive index gradient layer has a refractive index which decreases in a growth direction, depositing an organic layer above the refractive index gradient layer, and producing a nanostructure in the organic layer by a plasma etching process.

  • Patent number: 8217483
    Abstract: A semiconductor component that includes a photosensitive doped semiconductor layer, in which electrical charge carriers are released during absorption of electromagnetic radiation is disclosed. The photosensitive semiconductor layer has a structured interface and at least one layer which generates an electric field for separating the released charge carriers disposed downstream of the structured interface. The electric field extends over the structured interface. The photosensitive semiconductor component is distinguished by a high efficiency of the charge carrier separation, in particular, for generating an electric current.

  • Publication number: 20090053465
    Abstract: An optical element or component having excellent anti-fog effects as well as excellent scratch resistance and/or reflection reducing effects and optionally also hydrophobic and/or oleophobic properties, and a method for producing such an optical element or component. The element or component includes, in the following order, a glass substrate, a water-absorbing first layer, and a second layer selected from (i) an anti-reflecting coating; a mirror coating and a hard layer; (ii) a compound and/or combination of a hard layers and anti-reflecting coatings; and (iii) a compound and/or combination of hard layers and mirror coating. Blind holes or bores are introduced into the second layer and the water-absorbing first layer with the holes opening out from the second layer and extending completely through the second layer, and at least partially through the water-absorbing first layer.
