Structure and Electrical Properties of (Mg/ZrO2)52 Multilayer Nanostructures

(Mg/ZrO 2 ) 52 multilayer nanostructures with different thicknesses of Mg layers and the same thickness of ZrO 2 layers are obtained via the ion-beam sputtering of two targets in an argon medium. The thickness of one bilayer (Mg + ZrO 2 ) varies from 3.6 to 8.5 nm. It is found that using zirconium d...

Summary:(Mg/ZrO 2 ) 52 multilayer nanostructures with different thicknesses of Mg layers and the same thickness of ZrO 2 layers are obtained via the ion-beam sputtering of two targets in an argon medium. The thickness of one bilayer (Mg + ZrO 2 ) varies from 3.6 to 8.5 nm. It is found that using zirconium dioxide prevents the oxidation of the magnesium phase. An electric percolation threshold is observed when the morphology of magnesium layers changes (a transition from discrete to continuous morphology) as a result of an increase in the bilayer thickness. A change of the electrotransport mechanism is identified in the (Mg/ZrO 2 ) 52 multilayer nanostructures upon passing through the percolation threshold.
