Personale docente

Giovanna Sozzi is currently Associate Professor at the Department of Engineering and Architecture of the University of Parma, scientific disciplinary field ING-INF/01 Electronics. She is also a member of the Board of Lecturers of the PhD in Information Technology. Since 2018, she has been delegated, for the Orientation and Tutoring of the Degree Course in Electronics, the Degree Course in Communication Engineering, the Degree Course in Computer, Electronics and Telecommunications Engineering. Since 2018 he has also been the contact person for the activities of Alternanza Scuola Lavoro, now PCTO, for the Master's Degree Course in Electronic Engineering.

He graduated in Electronic Engineering (with honors) in 1997 at the University of Parma. During 1998 he worked at FIAT spa, Turin. From 1998 to 2001 he attended the PhD in Information Technology (XIV cycle) at the Department of Information Engineering of the University of Parma. Between 1999 and 2000 he collaborated with Procter & Gamble Italia spa, Nelsen plant in Gattatico (RE). In November 2001 she collaborated with INFM UdR of Parma (National Institute for the Physics of Matter - Research Unit of Parma) for the development of process techniques for test structures of group III/V semiconductor. In November 2001 he won a twelve-months CNR-MADESS II scholarship in the area of "Reliability and Physics of Failure Mechanisms of Compound Semiconductor Electronic Devices", at the Department of Engineering Sciences - University of Modena and Reggio Emilia. In January 2002 he obtained the title of PhD, discussing a thesis on heterojunction devices of compound semiconductors. In September 2002 she became a Researcher at the Faculty of Engineering of the University of Parma, in the ING/INF-01 "Electronics" scientific-disciplinary field.

From aa. 2002/2003 she has been teaching at the University of Parma, first in the field of Industrial Electronics for the University Master's Degree Course in "Electronic Technologies for Industrial Innovation", and then in the Degree Courses of the Information Engineering sector.

 The main research activities were concerned with I) the characterization and numerical simulation of III-V compound semiconductor devices for microwave applications with special attention to the study of breakdown, hot electron and trap state phenomena and their impact on the reliability of heterostructure devices, as well as the electro-thermal simulation, both two-dimensional and three-dimensional, of FET and HBT; (II) electro-thermal and thermal simulations of silicon diodes and resistors for high power applications; (III) electro-thermal numerical simulations, both 2D and 3D, of GaN devices; (IV) compact models of HEMT dispersive effects on GaN; (V) modelling and numerical simulations of thin-film solar cells.

Giovanna Sozzi has participated in numerous research funded projects. In 2010, the project entitled: "Study and optimization of innovative low-cost solar cells for the mass market", for which she was the principal investigator, was funded by the Fondazione Cariparma. In May 2015 the project entitled "Super high efficiency Cu(In,Ga)Se2 thin-film solar cells approaching 25% (acronym "Sharc25") 42 months-long, was funded under HORIZON 2020 (H2020) Framework Programme for Research and Innovation (2014-2020) of the European Union.

Currently the research interests follow two main strands: 1) second and third generation thin-film solar cells with particular reference to device analysis that yields insight into internal operation of the device through one-, two- and three-dimensional modeling to understand current devices, guide progress and help to interpret experimental characterization techniques; 2) silicon carbide (SiC) wide energy-gap devices, with particular reference to the electrical measurement of lifetime in 4H-SiC devices using OCVD technique. She authored numerous scientific publications in international journals and presented at international conferences. She also cooperates as reviewer with international journals, such as Solar Energy Materials and Solar cells, IEEE-Journal of Photovoltaics, Optik.
