ULTRA-THIN DOPED NOBLE METAL FILMS FOR OPTOELECTRONICS AND PHOTONICS APPLICATIONS

摘要

Silver (Ag), and aluminum (Al), titanium (Ti), nickel (Ni), chromium (Cr), gold (Au), magnesium (Mg), tantalum (Ta), germanium (Ge), or combinations thereof Electrically conductive thin and smooth films comprising a conductive metal such as In other alternative variations, gold (Au) or copper (Cu), and aluminum (Al), titanium (Ti), nickel (Ni), chromium (Cr), gold (Au), magnesium (Mg), tantalum ( Electrically conductive thin and smooth films such as Ta), germanium (Ge), or a combination thereof are provided. These materials have good electrical conductivity, can be very thin, flexible and transparent, and have low light loss. Methods of making the films and assemblies comprising such films are also provided. The assemblies can be used, in particular, in optical metamaterials exhibiting high transmittance and uniform response, or in photovoltaic cells and light emitting devices with high power conversion efficiency.
