The insertion of an ultra-thin sublayer of intentionally oxygen-doped aluminum nitride can drastically improve the adhesion between an intentionally stoichiometrically deposited aluminum nitride and a silver functional layer of a low-emissivity solar-control structure. A similar sublayer, optionally disposed above the functional layer, can improve the adhesion between the silver and top layers of the structure. Additional benefits of inserting the aluminum-oxy-nitride include an improved smoothness of the interface, reduced electron scattering, and better performance of the structure in both visible and infrared spectral regions.
