"Islands of Porphyrin Molecules in a Sea of Surface State Electrons"

Mr Willi Auwarter. TUM (Germany)



STM
Image Description:
This STM image shows highly ordered, self-assembled islands of porphyrin molecules on a silver surface. The achieved intramolecular resolution allows to identify the terminal groups (four protrusions) of these functional molecules. Furthermore, the interaction of the molecular islands with the supporting surface is visualized by the standing wave pattern of scattered surface state electrons.
