Investigation of Growth Mechanism of Thin Sputtered Cerium Oxide Films on Carbon Substrates

Popis výsledku v původním jazyce

In this study we present a method of fabrication of nanoporous and nanostructured layers of cerium oxide on carbon substrates via radio frequency (rf) magnetron sputtering which is a technique suitable for commercial use in contrary to other techniques commonly used for preparation of nanostructured catalysts. Roughening of deposited layers is shown to be dependent on sputtering conditions and the amount of deposited material. Optimization of these parameters results in growth of mushroom-like structures consisting of carbon base with a mantle of crystalline cerium compounds. With higher amount of deposited cerium oxide the structures start to be interconnected at their tops due to coalescence of cerium based particles forming characteristic ridged surface observable from a topographic view. Amorphous carbon layers sputtered on a silicon wafer were used as a substrate for further analysis. Measurements of the final thicknesses of cerium oxide/amorphous carbon bi-layers point to the fac
