title: Controlling the electronic interaction between a molecular wire and its atomic scale contacting pad.
abstract: We report a quantitative study on the electronic interaction between a molecular wire and its atomic scale metallic contacting pad. A so-called "reactive Lander" molecule is manipulated using a low-temperature scanning tunneling microscope to form a planar one-end electronic contact. The increase of the STM contrast at the junction location is discussed by means of the electronic interaction between the contacting group of the molecular wire and the end atoms of the nanopad.
