Abstract
In this paper we discuss the near-room-temperature electrical transpor t characteristics of structures made from ligand-stabilized metal clus ters. The structures show threshold behaviour, nonlinear current-volta ge characteristics and radio-frequency-induced plateaux consistent wit h Coulomb-blockade-dominated transport in disordered arrays of metal d ots. Samples having triphenylphosphine and octadecanethiol ligand shel ls are found to have a 3 orders of magnitude difference in current abo ve threshold. We discuss a possible explanation for this observation.
