Abstract

The tunneling differential conductance of Pd-ZrO2 thin granular films prepared by RF sputtering has been measured. We found that the temperature dependence of at zero bias reveals the presence of thermally assisted tunneling. The dependence of differential conductance on applied voltage shows a parabolic background which reveals the presence of elastic tunneling in the high-temperature range (265-286 K). Below a dip, superimposed to the parabolic background, develops and the increase of at low voltage is caused by Coulomb blockade. This behavior can be described by the scaling law , which was already found in other granular materials. © Copyright EPLA, 2013.
