Structural and electronic properties of Ir nanowires on Ge(100) — •René Heimbuch, Iris Slootheer, and Harold Zandvliet — Physics of Interfaces and Nanomaterials, MESA+ Institute for Nanotechnology, University of Twente

Iridium (Ir) nanowires show structural and electronic properties that are potentially of large interest for nano-electronic applications. Here we present detailed studies on the structural evolution of the surface and the growth of Ir nanowires on Ge(100). Using Scanning Tunneling Microscopy at low temperatures, we probed the wires and mapped the electronic landscape on and around the atomic chains. The wires show electronic properties that are very distinctive from the surrounding. A strong metallic character of the Ir nanowires promotes the Ir/Ge(100) system to a potential candidate for exotic low dimensional electronic effects.
