Nanowires and method for the production there of

摘要

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.

主权项

1. A nanowire structural element that includes:
an array of numerous neighboring segmented nanowires of electrochemically depositioned material, including alternating sequences of numerous first segments having first diameters and numerous second segments having second diameters, wherein the first diameters are larger than the second diameters, such that the nanowires have segmented structures in the lengthwise direction, wherein the second segments form connecting pieces between the first segments, and at least one substrate layer to which the nanowires, in each case, are firmly joined, wherein the array includes the nanowires integrally formed to two substrate layers to define space between the substrate layers.
