MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
0.0 out of 5 stars
25 Feb 2008 | Online Presentations | Contributor(s): Bhaskaran Muralidharan, owen miller, Neeti Kapur, Avik Ghosh, Supriyo Datta
We first outline the qualitatively different physics involved in the charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) self-consistent field (SCF) and the weakly coupled (strongly interacting) Coulomb Blockade (CB) regimes. The CB...

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?...
