Typically, metal–molecule–metal junctions are measured using a break-junction method where electrode separation is mechanically evolving during measurement. Here, to probe the impact of the junction geometry on conductance, we apply a sinusoidal modulation to the molecular junction electrode position. Simultaneously, we probe the nonlinearity of the current–voltage characteristics of each junction through a modulation in the applied bias at a different frequency. In turn, we show that junctions formed with molecules that have different molecule–electrode interfaces exhibit statistically distinguishable Fourier-transformed conductances. In particular, we find a marked bias dependence for the modulation of junctions where transmission is mediated thorough the van der Waals (vdW) interaction. We attribute our findings to voltage-modulated vdW interactions at the single-molecule level.","lang":"eng"}],"date_created":"2024-09-06T12:58:41Z","external_id":{"pmid":["36602221"]},"date_published":"2023-01-05T00:00:00Z","publication":"Nano Letters","date_updated":"2024-11-25T14:49:19Z","extern":"1","year":"2023","citation":{"short":"Y.
