The invention relates to the production of segmented nanowires and components having said segmented nanowires. A template-based method is preferably used for producing the nanowire structural element, wherein electrochemical deposition of the nanowires takes place in nanopores. A plurality of nanowires thus is generated in the template foil. For the electrochemical deposition of the nanowires, analternating sequence of cathodic deposition pulses and anodic counterpulses is performed. Segmented nanowires can be produced thereby.
