Metallic Chains on Ge (001) Surface and Their Manipulation — •Deniz Aşan Acar¹, Umut Kamber¹, Dilek Yildiz², and Oğuzhan Gürlü¹ — ¹Istanbul Technical University, Istanbul, Turkey — ²University of Basel, Basel, Switzerland

One dimensional, single atom thick wires present an exotic playground. We investigate the surface structure formed by adsorption of Pt and Au on Ge(001) surface. It is well known that upon annealing of Pt deposited Ge(001) surface at 1000 K atomic chains form along with two different types of terraces. Similar structures form due to Au deposition on Ge(001). In this study we have experimented on the co-deposition of Au and Pt on to Ge(001) surfaces. We will report on our findings related to the formation of novel atomic scale structures. (This study was funded by a TUBITAK 1001 project with grant number 112T818.)
