    Abstract: Methods for forming a coating over a surface are disclosed. A method includes directing a first source of barrier film material toward a substrate in a first direction at an angle θ relative to the substrate, wherein θ is greater than about 0° and less than about 85°. Additionally, a method of depositing a barrier film over a substrate includes directing a plurality of N sources of barrier film material toward a substrate, each source being directed at an angle θN relative to the substrate, wherein for each θN, θ is greater than about 0° and less than about 180°. For at least a first of the θN, θN is greater than about 0° and less than about 85°, and for at least a second of the θN, θN is greater than about 95° and less than about 180°.

    Abstract: A device includes a first electrode, an organic layer disposed over the first electrode and a second electrode disposed over the organic layer. The second electrode includes a first conductive layer, a first separation layer disposed over the first conductive layer, and a second conductive layer disposed over the first separation layer, wherein the first separation layer is not a continuous layer and the first and second conductive layers are bridged where the first separation layer is not continuous. The first separation layer has an extinction coefficient that is at least 10% different from the extinction coefficient of the first conductive layer at wavelength 500 nm, or an index of refraction that is at least 10% different from the index of refraction of the first conductive layer at wavelength 500 nm.
