Abstract: Apparatus for galvanically growing a plurality of nanowires on a substrate, comprising a substrate holder and a housing, in which a chamber, a control unit and a storage tank for an electrolyte are arranged, the apparatus being designed to grow the plurality of nanowires from the electrolyte onto the substrate when the substrate holder with the substrate has been inserted into the chamber.

Abstract: Method for galvanically growing a plurality of nanowires on a substrate, comprising a) placing a foil onto the surface, the foil having a plurality of passing-through pores, in which the nanowires can be grown from an electrolyte, b) placing an elastic element that is permeable to the electrolyte onto the foil, the electrolyte being brought into contact with the foil by way of the elastic element, c) for a first growing time period, galvanically growing the plurality of nanowires, d) removing the elastic element, and e) for a second growing time period, continuing the galvanic growing of the plurality of nanowires.

Abstract: Apparatus for galvanically growing a plurality of nanowires on a substrate, comprising a substrate holder and a receptacle for the substrate holder, the apparatus being designed to grow the plurality of nanowires on the substrate when the substrate holder with the substrate has been received in the receptacle, the substrate holder having electronics which are designed to influence the growing of the nanowires.
