摘要

In this paper, we report on a process to prepare gold nanoparticle stripes on Si02 by convective/capillary assembly without any patterning of the substrate. Electrical devices were then fabricated using stencil lithography in order to avoid any contamination. I (V) measurements at room temperature show that these stripes have an ohmic behavior between ±0.5 V with a resistivity ranging from one to two orders higher than the gold bulk value. Furthermore, I (V) and I(t) measurements reveal current fluctuations that were interpreted in terms of charging and discharging of nanoparticle islands leading to a very large electrostatic perturbation of current conduction paths. Unconventional relative amplitudes of up to 99% RTS fluctuations were observed.
