Multilayer metallic electrodes for optoelectronics

摘要

The invention relates to an electrode comprising a substrate (1) and a layered structure comprising an electrically conductive film (2) in contact with at least one ultra thin metal film (3), wherein the two films (2,3) are of different materials and
- said electrically conductive film (2) is selected from Cu, Au, Ag, Al
- said ultra thin metal film (3) is selected from Ni, Cr, Ti, Pt, Ag, Au, Al and their mixtures. The electrode is particularly useful for optoelectronic devices and shows good conductivity, transparency and stability.
