Giovanni Bertoni

Short Bio

2003 - PhD in Physics from the University of Milan with a thesis on nanostructured carbon films studied with microscopy and spectroscopy techniques.

2003 – 2008. Post-Doc fellow in advanced transmission electron microscopy (TEM/STEM) and EELS spectroscopy, at CEMES (CNRS) in Toulouse (France) and EMAT at the University of Antwerp (Belgium).

2008 – 2011. Scientist at the Italian Institute of Technology (IIT) in Genova, involved in the setup of an advanced electron microscopy laboratory, including the first microscope with image aberration correction in Italy.

From 2012. Researcher at CNR. Giovanni has great experience in high-resolution transmission electron microscopy (TEM) and scanning (STEM) microscopy techniques, combined with electron energy loss spectroscopy (EELS), both theoretically and experimentally, and applied in particular to the study of nanostructured materials. Giovanni is co-author of more than 100 scientific articles.

Research Interests

  • Characterizations of nanostructures by high-resolution transmission electron microscopy (HRTEM)
  • Quantitative electron microscopy by Exit-Wave (EW) reconstruction in HRTEM
  • Quantitative electron microscopy by ADF-STEM and image simulation
  • 3D imaging of nanostructures by transmission electron tomography (ET)
  • Chemical quantification and modeling of electron energy-loss spectroscopy (EELS) in the transmission electron microscope
  • Orbital Angular Momentum selection in electron scattering (OAM-EELS)
