Abstract
Multilayer metallo-dielectric energy control coatings are disclosed in which one or more layers are formed from a hydrogenated metal nitride dielectric, which may be hydrogenated during or after dielectric deposition. Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer. Electrical busbars and micro-nano electrical grids may be integrated with one or more metal layers to provide functionality such as de-icing and defogging.
