Introduction to Molecular Conduction
21 Jul 2005 | | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Avik Ghosh, Supriyo Datta
A scanning probe microscope brushes the tips of molecules rising up from a gold substrate. After making contact, the probe measures a very strange current-voltage relationship--linear portions separated by flat spots or sharp increases. Definitely not Ohm's law. Is the experiment correct?...
