We examined charge transport properties of two gold nanoparticles (GNPs) in a nanogap transistor with a gap width of ∼10 nm. The GNPs connected to each other and to outer electrodes through a small number of dithiolated terthiophene wire molecules as a tunneling barrier. The transport property measured at 11 K was analyzed based on the theory of double-dot single-electron transistors and inelastic cotunneling. The results clearly show mutual Coulomb interactions between the two GNPs. Moreover, we found the appearance of superperiodic conductance, because of differences in the charging energy of the two GNPs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
