Abstract

In this work we report the morphological, structural and luminescence properties of HfO₂ nanocrystals grown on the surface of SiC/SiO₂ core/shell nanowires by atomic layer deposition. All the studies are carried out in comparison with HfO₂ nanocrystal aggregates grown on planar oxidized silicon substrates. The structural analyses reveal that HfO₂ has monoclinic structure with different orientations. The cathodoluminescence emission shows the main components at 2.7 and 2.3 eV, deeply influenced by the arrangement and aggregation of the nanocrystals.
