Publikováno v: AIP Advances, Vol 2, Iss 3, Pp 032108-032108-8 (2012)

We propose an interpretation of the voltage creep observed in metallic grain assemblies based on the sensitivity of the electrical properties to the surface topology of the beads. From the real area of contact between adjacent beads, directly measure
