Maurizio De Crescenzi is full professor of Structure of Matter at Roma "Tor Vergata" University, Roma. He leads a group on Nanostructures and Materials Science at the Department of Physics. His expertise in Surface Science and Materials Science using Electron Energy Loss, XPS, STM is internationally recognized. He has developed the Extended Energy Loss Fine Structure, an electron spectroscopy technique as a local surface structural tool. His main fields of investigation are: growth of nanostructures of Ge/Si and Fe/Cu/Si ultrathin films by MBE (Molecular Beam Epitaxy), synthesis of silicon carbide nanostructures and carbon nanotubes, photovoltaic and optoelectronic investigation of carbon nanotubes and graphene. More recently he has synthesized silicene nanosheets on inert substrates. He has organized several international conferences on nanostructures, published about 300 papers and written a book on electron spectroscopy. He has in the editorial board of Nature Scientific Reports. He has received a Laurea Honoris Causa from Aix-Marseille University for his important contributions on the developments of nanomaterials.
