As the performances of the transistor are approaching their physical limits, developing semiconductor technology with novel concepts and materials is a major focus of the microelectronics research and industry. In recent years, MOSFETs fabricated with semiconducting 2D transition metal dichalcogenide (TMD) channels have been identified as promising candidates to reach the ultimate gate length scaling, […] >>

This thesis concerns the field of HgCdTe infrared detectors for astrophysical applications, for which the Infrared Laboratory of CEA -Leti is a world leader. The student will join the infrared laboratory which includes the entire detector manufacturing process. He will produce the samples using the technological means of elaboration available in the Leti clean room. […] >>

Sodium-ion batteries can compete with Li-ion batteries for power applications, while being free of critical metals such as Co, Ni or Li. However, fast charging can lead to inter- and/or intra-particle reaction heterogeneities causing underutilisation of the electrode and/or mechanical degradation involving particle cracking. These complex non-equilibrium processes can have profound effects on the overall […] >>

This thesis focuses on the study of unconventional topological spin textures present in antiferromagnetic thin film materials. In the field of spintronics, spin correlations have attracted considerable attention, facilitating progress in fundamental physics and the development of new applications. Some effects, such as the topological Hall effect, are related to the specific local arrangement of […] >>

The recent improvements of quantum bits (qubit) based on electron spins pave the way towards their massive integration into the possible quantum processor of the future quantum computer. The individual biasing, manipulation and reading of particular qubits of the matrix is a key point that forges strong links between physicists and electronics engineers. More specifically, […] >>
