Transport through a single octanethiol molecule.
Octanethiol molecules adsorbed on Pt chains are studied with scanning tunneling microscopy and spectroscopy at 77 K. The head of the octanethiol binds to a Pt atom and the tail is lying flat down on the chain. Open-loop current time traces reveal that the molecule wags its tail and attaches to the scanning tunneling microscopy-tip resulting in a dramatic increase of the current. We measured a single molecule resistance of 100-150 Mohms.
