Abstract

By means of integral temperature dependent conductance measurements, the effective capacitance of ligand stabilized nanoparticles, arranged in dense packings or networks, can be deduced from the activation energy of the charge transport, for which the use of the Landauer formula is proposed. According to this, the barrier resistance in ligand stabilized nanoparticle arrangements depends predominantly on the inter particle spacing rather than on the chemical composition of the molecules. Comparison with data of the single molecule resistance determined by local probe techniques or by theoretical methods shows remarkable aggreement.
