Abstract:
1. A multilayer electrically conducting thin film having an optical-transparency of at least 50% for at least a selected band of wavelengths between 400 nm and 25 microns, the multilayer film comprising: an adhesion-enhancing optical-matching layer deposited directly on a supporting surface and having a thickness of not more than 60 nm; a metallic conduction layer deposited directly on the adhesion-enhancing optical-matching layer and having a thickness of at least three and not more than 60 nm; and an anti-reflective overcoat layer comprising an oxide and deposited directly on the metallic conduction layer, the overcoat layer having a thickness of at least 3 and not more than 120 nm.
