Abstract

Low-dimensional transition metal oxide nanostructures supported on metal templates constitute novel hybrid systems with high potential for applications in nanotechnology and for fundamental research on emerging phenomena at the nanoscale. This seminar focuses on Mn, Ni and Co oxide nanostructures assembled into model configurations in ultrahigh vacuum and on the controlled assessment of their properties by exploiting a full set of modern surface science tools. Due to the reduced dimensionality these structures contain a large number of undercoordinated atoms; moreover, the interfacial interaction with the substrate provides constraints on the geometric structure, typically resulting in elastic strain and/or uncompensated charge. These factors may modify significantly the physical and chemical behaviour of the nanosystems with respect to the parent bulk oxides.
