Low Temperature STM investigation of pentacene molecule on Cu3Au(100) — •Micol Alemani, Francesca Moresco, Leo Gross, and Karl-Heinz Rieder — Inst. für Exp.physik, FU Berlin, Arnimallee 14, D-14195
The adsorption geometry of pentacene molecules on Cu3Au(100) is studied by means of a Low-Temperature Scanning Tunneling Microscope. The Cu3Au(100) is terminated by the gold-rich plane, as already known and as probed by atomic resolution images. Depending on the substrate geometry the molecules exhibit two different orientations and conformations. Thanks to the stability of the system at low temperature (7 K), it has been possible to perform controlled manipulation of single pentacene molecules. The study of the manipulation of pentacene on Cu3Au(100) is presented.
