An electrical transition induced by an electric field was observed in a device consisting of a polystyrene film containing dodecanethiol-capped Au nanoparticles. When the current through the device was not limited during the voltage sweep, the resistance decreased irreversibly by around two orders of magnitude. Reversible resistance changes were observed when the compliance current was set within an appropriate range. The ratio of the resistance of the more conductive state and that of the less conductive state was around one order of magnitude. The resistance of the more conductive state decreased with the increase in the compliance current, but did not depend on the device area. Both states were stable for more than $10^{5}$ s. These results suggest that this bistability may be attributed to the filament formation within the polystyrene film.
