The nanostructural origin of the ac conductance in dielectric granular metals: the case study of Co_20(ZrO_2)_80

Z Konstantinovic, M Garcia del Muro, X Batlle +2

We show which is the nanostructure required in granular Co20(ZrO2)80 thin films to produce an ac response such as the one that is universally observed in a very wide variety of die…
