* presenting author:Andre GOURDON,
Addressing a single atom or a single molecule on a surface from the human scale is a prerequisite for electronics and mechanics at the single atom or molecule level. It requires atomically precise the fabrication of the devices in ultra-high vacuum. In this talk, I will present the recent results obtained in the frame of a large european project (PAMS) involving eight research groups working on planar atomic and molecular scale devices. Will be detailed: the addressing by 4-probes UHV-STM techniques, the preparation of contact nanopads, the STM lithography to fabricate extended dangling bond wires, the on-surface synthesis of large molecular wires and gates, and the coupling between molecules and surface dangling bonds.
