Abstract
We present the formation of an ordered threedimensional lattice of Ni nanocrystals in an amorphous alumina matrix by a selfassembly process The selfassembled growth achieved by singlestep magnetron sputtering deposition of a Ni/Al2O3 multilayer is driven by surface morphology effects The influence of the Ni layer thickness on the Ni particle size separation and quality of ordering is examined The quality of Ni nanoparticles ordering in alumina is compared to their ordering in a silica matrix The obtained results are important for the understanding of the selfassembly process of metallic particles in amorphous matrices and the applications of such materialsThis work has been supported by the Ministry of Science Education and Sports Croatia project numbers 09809828862895 09809828862859 09811910052876 and 03503528432844 and the Unity Through Knowledge fund through the grant no 66/10 The authors thank Aleksa Pavlešin for the help in the sample preparation as well as Annette Kunz and Martina Missbach for the TEM specimen preparation
