TEM study of electrodeposited Ni/Cu multilayers in the form of nanowires

Ni/Cu multilayers were electrodeposited within nanopores of polycarbonate membranes. Morphology of the obtained nanowires, which are 60 similar to 80 nm in diameter and similar to 5 mu m in length, has been studied by transmission electron microscopy. It has been observed that the thickness of Ni/Cu layers increases as the nanowire is growing; Ni layers and Cu layers grow epitaxially and the multilayers have a preferred growth direction [111] parallel to the wire axis.
