Electric-Current-Driven Molecular Rotor Boosts Conductance

Electric-Current-Driven Molecular Rotor Boosts Conductance

Researchers report a torque-driven molecular machine using a helicene molecule suspended between electrodes, where applied voltage induces cyclic, unidirectional rotation reversible by polarity. Above a threshold, rotation enhances conductance, and the onset can be tuned by stretching or compressing the molecule, with calculations explaining the motion and current increase.
