Abstract:
1. Method for depositing a layer at a substrate, the layer containing at least two components co-deposited by at least two evaporation sources, wherein the mixture of the components regarding the content of the components is set by tilting the evaporation sources to a predetermined angle, wherein a concentration profile of the components in the layer is set by variation of the tilting angle of the evaporation sources during deposition, wherein the concentration profile of the components comprises a gradient with increasing or decreasing content of a specific component in the layer across a thickness of the layer, wherein setting the evaporation source is based on information with respect to at least one of the deposition condition selected from the group consisting of: type of evaporation source, geometry of evaporation source, position of evaporation source, evaporation material, evaporation rate, evaporation temperature and form of the evaporation plume.
