A process for producing a nanoelement arrangement and to a nanoelement arrangement. A first nanoelement is at least partially covered with catalyst material for catalyzing the growth of nanoelements. Furthermore, at least one second nanoelement is grown on the catalyst material.Also, a nanoelement arrangement having a first nanoelement on which at least one predetermined region is covered with catalyst material for catalyzing the growth of nanoelements, and at least one second nanoelement grown on the catalyst material.
