Speaker: Javier Fernandez Lozano, University of Santiago de Compostela (USC), Spain

The session will focus on Silvaco TCAD simulation tools, detailing the models and parameters of the SiC polytypes used in the simulations. It will also explore the optimization algorithms and visualization tools employed for analysing and refining device performance.

The rePowerSiC webinars are expert-led sessions which provide in-depth insights. The 1st webinar is about simulation and optimization tools for silicon carbide converters in high power laser transmission application, as developed within the RePowerSiC project.

Javier Fernandez Lozano is a postdoctoral researcher at the University of Santiago de Compostela (USC). He holds a degree in Physics and pursued a Master’s in Materials Physics at the same institution. Alongside his academic work, he co-founded a science outreach startup, while also playing with his music band across the Iberian Peninsula. Following the COVID-19 pandemic, he returned to academia, completing a Master’s in Renewable Energy, Sustainability, and Climate Change at USC. In 2021, he began his PhD in Renewable Energy, successfully defending his thesis in December 2024. During his doctoral studies, he conducted a research stay at the Technical University of Denmark (DTU) in Copenhagen and received two consecutive awards at the Optical Wireless and Fiber Power Transmission Conference (OWPT) in Yokohama. His expertise lies in semiconductor device modeling, particularly in photovoltaics, and optimization algorithms.

This webinar provides a detailed examination of the modeling insights for power converters within the RePowerSiC project. It will cover the TCAD Silvaco simulation tool, including the models and parameters of the silicon carbide (SiC) polytypes used in the simulations. Additionally, the optimization algorithms employed in the study will be thoroughly discussed. The session will conclude with an explanation of the analysis and visualization tools used for global optimizations before final delivery to the consortium. Attendance is highly recommended for consortium members involved in the fabrication and processing of power converters, as the content is directly relevant to their work, and to any other researchers interested in learning the basics of TCAD modelling for power converters.
