Some more power is needed to maintain a stationary charge distribution for circulating a current in a quantum device. This effect is a result of the quantum collision current originating from inelastic scattering, which contributes to the observable current density. The picture shows a molecular circuit consisting of a self‐assembled monolayer of benzene dithiolate molecules in contact with two gold electrodes.
