The invention concerns the production of segmented nanowires and components having said segmented nanowires.For the production of the nanowire structural element, a template based process is used preferably, wherein the electrochemical deposition of the nanowires in nanopores is carried out. In this manner, numerous nanowires are created in the template foil.For the electrochemical deposition of the nanowires, a reversed pulse procedure with an alternating sequence consisting of cathodic deposition pulses and anodic counter-pulses is carried out. By this means, segmented nanowires can be produced.
