Dr. Giacomazzi's current interests mainly concern defects in glasses. He is currently working on a research project dedicated to color centers in vitreous silica (v-SiO2), the understanding of which is of paramount importance for improving the performances of silica-based optical fibers as well as microelectronic devices. This is especially true for applications in harsh-environments where a high concentration of these radiation-induced defects can stop the normal functioning of silica-based devices. In particular, a class of paramagnetic color centers in v-SiO2, i.e. the E' centers, will be investigated by means of first-principles calculations of electron paramagnetic resonance (EPR) parameters by using the Quantum-Espresso package.
Dr Giacomazzi obtained the degree of "Docteur Es Sciences" (PhD) at the Swiss Federal Institute of Technology in Lausanne (EPFL) in 2007, with a thesis dedicated to the first principle modeling of the vibrational spectra of tetrahedrally-bonded glasses: SiO2 , GeO2 , and GeSe2. He then moved to ICTP (Trieste, Italy) where he carried out research on both high pressure physics and glass physics. During this period his investigations ranged from the high pressure phases of gypsum, to the dislocations in coesite and to the investigation of a technologically important material such as amorphous silicon nitride. After moving to SISSA (Trieste, Italy), his interests concerned the applications of Many Body Perturbation Theory for calculating the electronic properties of glasses and also of large molecules. In the last years, as IOM-Democritos PostDoc, he has carried out research on the origin of paramagnetic centers in pure and doped silica. Dr Giacomazzi is author of more than ten publications on international peer-reviewed journals.
