A method for producing a hybrid structure, the hybrid structure including at least one structured Majorana material and at least one structured superconductive material arranged thereon includes producing, on a substrate, a first mask for structured application of the Majorana material and a further mask for structured growth of the at least one superconductive material, which are aligned relatively to one another, and applying the at least one structured superconductive material to the structured Majorana material with the aid of the further mask. The structured application of the Majorana material and of the at least one superconductive material takes place without interruption in an inert atmosphere.

A method for producing a planar free surface comprising embedded, contactable nanostructures includes arranging at least one nanostructure on a surface of an initial substrate; applying a first layer to the surface of the initial substrate, wherein the first layer embeds the at least one nanostructure; applying a target substrate to the first layer; and separating the initial substrate from the first layer such that the at least one nanostructure embedded in the first layer has a planar free surface. An additional layer is applied to the surface of the initial substrate before the at least one nanostructure is applied to the initial substrate, and in that the initial substrate is removed from the first layer using a solvent.

A high-frequency conductor having improved conductivity comprises at least one electrically conductive base material. The ratio of the outer and inner surfaces of the base material permeable by a current to the total volume of the base material is increased by a) dividing the base material perpendicularly to the direction of current into at least two segments, which are spaced from each other by an electrically conductive intermediate piece and connected both electrically and mechanically to each other, and/or b) topographical structures in or on the surface of the base material and/or c) inner porosity of at least a portion of the base material compared to a design of the base material in which the respective feature was omitted. It was found that, as a result of these measures concerning the design, it is possible to physically arrange the same amount abase material so that a larger fraction of the base material is located at a distance of no more than skin depth from an outer or inner surface and is thus involved in current transport. As a result, a lesser fraction remains unused as a function of the skin effect.
