Conducting transparent coatings and method for their production

摘要

Conducting transparent layer system comprises a silver layer (3) between two oxide layers (2, 4) on a substrate (1) and has a quantity coefficient of more than 0.0855 Ohm <-1> for the wavelengths 435, 545 and 610 nm at a flat resistance Rs of less than 2.9 preferably less than 2.5 Ohm sq. An Independent claim is also included for a process for the production of a conducting transparent layer system comprising applying the second oxide layer (4) using a pulsed direct current (DC) sputtering process or an alternating current (AC)-superimposed DC sputtering process.
