Welcome to the homepage of the group of Prof. Mazzarello

We investigate the properties of materials which are not only of
fundamental interest, but also have promising applications in the field
of nanoelectronics. For this purpose, we use state-of-the-art
computational methods based on density functional theory. Our research
interests include phase-change materials, graphene nanostructures,
topological insulators and self-assembled monolayers of organic molecules.
