Molecular Voltage Shift

From Physics.aps.org: Small changes in the configuration of a molecule can significantly influence its resistive behavior in a circuit.
Single molecules offer promise as components for nanoscale electronic circuits. Now, experiments with a molecule sandwiched between two metal electrodes show that a molecule’s conductance depends sensitively on its configuration. Sujoy Karan, at the University of Kiel in Germany, and colleagues report that bending the molecule shifts its most resistive portion from one electrode to the other. This effect could be used to engineer a molecular-scale potentiometer, a device whose variable resistance can be used to control the flow of current in a circuit.
