Abstract

The invention relates to a method for combinatorially producing a library of materials by means of an electrochemical deposition in an array. The inventive library is made from an array of containers that consist of an electroconductive material, are open to the top and are electroconductively connected to a shared current supply device and is made from a corresponding array of auxiliary electrodes that are electroconductively connected to a shared current supply device and are arranged in such a way that an auxiliary electrode plunges into a container respectively or can be introduced therein without touching said container. The inventive method comprises the following steps: filling the containers with electrolytes having different compositions and containing electrolytically separable elements and applying an electric voltage between the current supply devices of the containers and auxiliary electrodes for obtaining an electrolytic deposition on the surfaces of the containers.
