Major milestone in molecular electronics. Berkeley Lab and Columbia Uni team used a combination of gold electrodes and an ionic solution to create a single-molecule diode that outperforms the best of its predecessors by a factor of 50.

“Using a single symmetric molecule, an ionic solution and two gold electrodes of dramatically different exposed surface areas, we were able to create a diode that resulted in a rectification ratio, the ratio of forward to reverse current at fixed voltage, in excess of 200, which is a record for single-molecule devices,” says Jeff Neaton, Director of the Molecular Foundry. “The asymmetry necessary for diode behavior originates with the different exposed electrode areas and the ionic solution,” he says...
