General project description
Ultra thin metallic layers with substrate influenced structure and morphology are controlled to be manufactured and the electrical conductivity of these layers is to be examined. For some of the systems of interest there are already some measurements from the past years. Especially for the system Sn on InSb (110) a structural phase transition was observed. In the ongoing research this system is further investigated and particular the morphology of the grown film is considered for the first time. Surfactant mediated growth and forming of alloys are further points of interest. Bi-layers and Sn / Bi-alloys as well as other non-reactive metals such as Ag, In, Ga, and Pb are considered as candidates for further structure correlated conductivity investigations. In comparison to thin metal films, optical and magnetooptical properties and the electronic structure of cleaned metal surfaces are also investigated.
