Marco Bazzzan obtained his Physics degree in 2001 and his Material Scince PhD title in 2004 at the Padova University. Since 2022 is Associate Professor at the Physics and Astronomy Department.
His research interests are devoted mainly to solid state physics and optics. He worked on the experimental study of Lithium Niobate, a crystal material with several functional properties largely employed in nonlinear optics and photonics, in particular to its growth, structural analysis by high resolution X-Ray diffraction, photorefractive nonlinear optics and related microscopic phenomena and fabrication of integrated optical circuits. As INFN member He is also involved in the Virgo experiment for the detection of Gravitational Waves from Earth, with a research on the optical coatings used in those devices.
He collaborates with several italian and international laboratories on a number of research projects and at several large scale facilities (CERN, ESRF, EGO).
For the Padova University, He is responsible of the Advanced Laboratory B course and teaches in the "Advanced Optics and Metrology" course. He also gives several lessons at the course "Photonic Devices" for the master in Telecommunications and at the course "X-Ray techniques for material analysis" for the PhD school in Science and Engineering of Materials and Nanostructures.
He is co-author of more than 200 publications on international scientific reviews, which He collaborates with also as a reviewer.

Thesis proposals

1) Ferroelectric nanofilms for photovoltaics
Ferroelectric materials possess an electric dipole moment even at zero applied field. Among their multifarious applications they have recently been indicated as one of the most promising alternatives for solar energy conversion. Some experimental evidences suggest that the reduction of those materials to the nano-scale brings new physical phenomena, and some among them may lead to an increase of the conversion efficiency.
The proposed research activity has both experimental and theoretical aspects and contributes to this field with tasks ranging from fabrication and characterization to the study of transport phenomena at the microscopic level.

2) High-performance optical coatings for gravitational interferometry
The reflecting surface of the mirrors used in gravitational interferometers is constituted by optical thin films which are a key element of those devices. The Brownian noise associated to those materials defines the machine's sensitivity and thus the portion of universe observable with gravitational waves.
On the top of that, those materials must possess extreme optical properties to withstand the high power circulating in the interferometer.
In our laboratory we study the structure and properties of materials for this kind of applications, in close collaborations with other institutes belonging to the international networks involved in the commissioning of the LIGO, Virgo and KAGRA gravitational interferometers.
