Logical switching using one single molecule

"The single electron logic calculators (SELCs) are built from molecules bridging the gap between two gold electrodes. The layer of material has a thickness of one single molecule. It functions thanks to a quantum effect called the Coulomb blockade. Depending on voltage, the electron will be halted or flow through the molecule. As the effect mainly depends on voltage pulses and not on a continuous electric current, the consumption is very low"
