Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job description
Silicon carbide (SiC) components represent the future of power electronics, surpassing silicon technologies in terms of temperature tolerance and power handling capability. At the heart of this evolution, CEA Leti plays a key role in the development of these new generation components, essential for applications such as electric vehicles, charging systems or photovoltaic installations. Our teams provide support to major manufacturers European countries by establishing pilot production lines for GaN and SiC components, as well as by developing SiC substrates with our industrial partners
This thesis aims to develop innovative technological approaches for the design of SiC MOS transistor gates and to evaluate their environmental impact to inform our technological choices. You will deepen the understanding of the physics of SiC MOSFETs by examining different gate architectures. and in
identifying the physical processes that restrict electron mobility in a SiC MOS channel. Questions such as the influence of stress on mobility and the possibility of separating carrier mobility from threshold voltage will be at the heart of your research.
