Research experience

• Beamtimes at Elettra SR facility in Trieste in February 2011 (ALOISA), October 2010 (BACH beamline), July 2010 (ALOISA), February 2010 (BACH), December 2009 (ALOISA), July 2009 (GasPhase), October 2003 (SpectroMicroscopy), March 2003 (EscaMicroscopy), February 2003 (SpectroMicroscopy), April 2002 (EscaMicroscopy), October 2000 (VUV beamline)

• 1999 - Stage in the Twente University of Enschede (NL), with an Erasmus-Socrates fellowship. In this period I worked in the Solid State Physics group learning different surface science techniques: Thermal Helium Atom Scattering (TEAS); Spot Profile Analysis Low Energy Electron Diffraction (SPA-LEED); Auger Electron Spectroscopy (AES); Surface Magneto Optic Kerr Effect (SMOKE).

6. ID:20095173 Metalation of TPP and OEP with Fe atoms: high resolution photoemission and near edge x-ray adsorption spectroscopy sudy (Completed)

- High-resolution photoemission and X-ray absorption experiments performed with synchrotron light source to characterize the electronic and magnetic properties of thin films of organic compounds like porphyrins and metal-porphyrins on metal substrates.

- Scanning Tunneling Microscopy (STM) in air and vacuum environments on molecular thin films adsorbed on grafite (air experiments) and on clean metal surfaces (vacuum). The main present activity is the setting up of an STM laboratory where to perform imaging and tunneling spectroscopy experiments on metal-porhyrin complexes adsorbed on metals.

Research Activity (past)

- Frequency Modulation AFM for high resolution imaging and force spectroscopy in different environments.

- The main activity on the former AFM project has also required the developments of experimental skills in the field of mechanics and electronics (mechanical design and construction of scanner, piezo-tube, piezo motors; configuration and implementation of the home-buildt microscope with the commercial electronic apparatus)

- Experimental preparation of biological samples for imaging and spectroscopy.

- Conventional lab Photomission experiments on functionalized Si.

- Photoemission Microscopy and AFM imaging on CsI photocathods.
