A method of reproducing at least one single-walled carbon nanotube having predefined electronic properties or a plurality of single-walled carbon nanotubes having the same electronic properties, the method comprising the steps: a) preparing a dispersion from a liquid and from the at least one single-walled carbon nanotube having predefined electronic properties or from the plurality of single-walled carbon nanotubes having the same electronic properties; b) forming fragments of the at least one single-walled carbon nanotube or of the plurality of single-walled carbon nanotubes by an energy input into the dispersion; c) applying the fragments of the at least one single-walled carbon nanotube or of the plurality of single-walled carbon nanotubes from the dispersion onto a surface of a carrier as a starting layer for reproducing and orienting the fragments on the surface during the application from the dispersion so that the surface is intersected by a longitudinal axis of the fragments and the fragments are not oriented in parallel in a plane with respect to the surface of the carrier, wherein the fragments are oriented by self-organization on a gold layer applied to the surface of the carrier, or are applied to the surface of the carrier onto a surfactant layer formed by a surfactant contained in the dispersion and having a thickness that is less than a length of the fragments, on which the fragments of the at least one single-walled carbon nanotube are applied and oriented after drying of the surfactant layer and fixed to the carrier by the surfactant layer; d) introducing the fragments applied to and oriented on the carrier into an apparatus for chemical vapor deposition, with single-walled carbon nanotubes having the same electronic properties being extended in the apparatus for chemical vapor deposition, starting from the fragments serving as the starting layer, in a gas atmosphere containing carbon by means of chemical vapor deposition. a) preparing a dispersion from a liquid and from the at least one single-walled carbon nanotube having predefined electronic properties or from the plurality of single-walled carbon nanotubes having the same electronic properties; b) forming fragments of the at least one single-walled carbon nanotube or of the plurality of single-walled carbon nanotubes by an energy input into the dispersion; c) applying the fragments of the at least one single-walled carbon nanotube or of the plurality of single-walled carbon nanotubes from the dispersion onto a surface of a carrier as a starting layer for reproducing and orienting the fragments on the surface during the application from the dispersion so that the surface is intersected by a longitudinal axis of the fragments and the fragments are not oriented in parallel in a plane with respect to the surface of the carrier, wherein the fragments are oriented by self-organization on a gold layer applied to the surface of the carrier, or are applied to the surface of the carrier onto a surfactant layer formed by a surfactant contained in the dispersion and having a thickness that is less than a length of the fragments, on which the fragments of the at least one single-walled carbon nanotube are applied and oriented after drying of the surfactant layer and fixed to the carrier by the surfactant layer; d) introducing the fragments applied to and oriented on the carrier into an apparatus for chemical vapor deposition, with single-walled carbon nanotubes having the same electronic properties being extended in the apparatus for chemical vapor deposition, starting from the fragments serving as the starting layer, in a gas atmosphere containing carbon by means of chemical vapor deposition.
