The gold films consisted of 100 nm size islands, separated from each other by nanometer-size gaps. The thickness of PPy can be varied from 30 to 200 nm. The IV characteristics of these hybrid PPyAu nanostructures show strong non-linearity at low temperatures, and in particular for the more insulating samples. The hopping transport is further verified from the log I versus V1/4 plots. Furthermore, the IV data follow an empirical relation dlogI/dV1/4T1/2.", }
