Carbon

G. Messina and S. Santangelo are working at the University of Reggio Calabria (Italy) since 1988. Presently, they are Physics Professors at the Engineering Faculty of the University. Their research work has been always carried out in the field of Condensed Matter Physics. From more than 10 years their scientific interest is focussed on the analysis of C-based materials by Raman spectroscopy. They are engaged in several relevant research projects.

• Aid of scaling laws in the achievement of a well-controlled film deposition process.- A spectroscopic approach to carbon materials for energy storage.- Biocompatibility, cytotoxicity and bioactivity of amorphous carbon films.- Characterisation of the growth mechanism during PECVD of multi-walled carbon nanotubes.- Correlation between local structure and film properties in states in amorphous carbon materials.- Defects in CVD diamond films from their response as nuclear detectors.- Effects of nanoscale clustering in amorphous carbon.- Elastic and structural properties of carbon materials investigated by Brillouin light scattering.- Electrical resistivity and real structure of magnetron sputtered carbon films.- Formation, atomic structures, and properties of carbon nanocage materials.- Hard amorphous hydrogenated carbon films and alloys.- Ion microscopy on diamond.- Measurements of defect density inside CVD diamond films through nuclear particle penetration.- Laser ablation deposited CNx thin films.- Modelling of the transport properties of diamond radiation sensors.- Nucleation process of CVD diamond on molybdenum substrates.- Optical characterisation of high-quality homoepitaxial diamond.- Pulsed laser deposition of carbon films: tailoring structure and properties.- Raman spectra and structure of sp2 carbon based materials: electron-phonon coupling, vibrational dynamics and Raman activity.- Raman spectroscopy and optical properties of amorphous diamond-like carbon films.- Raman spectroscopy of CVD carbon thin films excited by near-infrared light.- The role of hydrogen in the electronic structure of amorphous carbon: an electron spectroscopy study.- UV-induced photoconduction in diamond.- Vibrational spectroscopy in ion irradiated carbon based thin films
