摘要: We examined charge transport properties of two gold nanoparticles (GNPs) in a nanogap transistor with gap width ∼10 nm. The GNPs connected to each other and outer electrodes through small number dithiolated terthiophene wire molecules as tunneling barrier. property measured at 11 K was analyzed based on the theory double-dot single-electron transistors inelastic cotunneling. results clearly show mutual Coulomb interactions between GNPs. Moreover, we found appearance superperiodic conductance, because differences charging energy
