摘要
The noise within the electrical current through single-molecule junctions is studied at cryogenic temperature. The organic sample molecules were contacted with the mechanically controlled break-junction technique. The noise spectra refer to a system where only few Lorentzian fluctuators occur in the conductance. The frequency dependence shows qualitative variations from sample to sample.
