项目摘要
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.
测量了Au单原子接触和Au/BdT/Au单分子结的高频电导。用断续结法制备了结,并用网络分析仪测量了其高达1 GHz的信号传输特性。结果表明,Au/Bdt/Au单分子结的导纳虚部和Au单原子接触的S_(21)参数的位相都表现出平坦的光谱,并在1 GHz内保持为零。结果表明,这些原子和分子大小的结在射频区域表现为纯电阻。
