Abstract

It is hard to avoid the scanning tunnelling microscope (STM) in the investigation of nanometre-scaled objects. For instance, dynamics and decay rates of electrons at metal surfaces can be analysed using the STM leading to insight into many-body phenomena. Further, a major challenge in surface science is the parallel fabrication of highly regular structures. The STM provides images of periodic patterns of molecule clusters and chains as adsorbed on vicinal surfaces. Future electric circuits may be assembled from atomic or molecular wires. What is the conductance of single atoms or molecules? By performing controlled mechanical contact with the STM tip to atoms and molecules these conductance measurements are feasible.
