Research Abstract |
Measurements have been made on the high-frequency electric conduction through Au single-atom contacts and Au/BDT/Au single-molecule junctions. Junctions are prepared using the break-junction method and their signal transmission characteristics up to 1GHz have been measured with a network analyzer. It is found that both the imaginary part of the admittance of Au/BDT/Au single-molecule junctions and the phase of the S21 parameter of Au single-atom contacts exhibit a flat spectrum and remain zero up to 1GHz. The results indicate that these atom- and molecule-sized junctions behave as pure resistance in the RF regime.
