Catalytic growth of ZnO nanostructures by r.f. magnetron sputtering

Catalytic growth of ZnO nanostructures by r.f. magnetron sputtering

<p>Abstract</p> <p>The catalytic effect of gold seed particles deposited on a substrate prior to zinc oxide (ZnO) thin film growth by magnetron sputtering was investigated. For this purpose, selected ultra thin gold layers, with thicknesses close to the percolation threshold, are d...
