The post-doctoral researcher will focus on the investigation of AFE layers based on HfO2 and/or ZrO2 obtained by ALD (Atomic Layer Deposition), which will be able to work as high-k dielectrics for high-density antiferroelectric (AFE) capacitances (>20 J.cm-3). For understanding and optimizing the AFE capacitances, it is mandatory to relate the structural, micro-structural and chemical […] >>

Improving the performance of power electronics components is a major challenge for reducing our energy consumption. Diamond appears as the ultimate candidate for power electronics. However, the small dimensions and the price of the substrates are obstacles to the use of this material. The main objective of the work is to overcome these two difficulties […] >>

The need for biological sensing solutions is constantly growing. Amid targeted applications, some require biosensor with high sensitivity. At CEA LETI we are running a project that aim at developing novel innovative wound dressing equipped with graphene biological sensors to track wound bacterial proliferation indicative of sepsis. The sensor is a Solution gated graphene FET-like […] >>

In the history of semiconductors, the requirements in terms of device size have always followed a descending trend. Low thermal budget solutions are now key to manage these specifications. Within this context, nanosecond laser annealing stands as an excellent solution. Laser process conditions can be adjusted to the material structure. During heating and according to […] >>

X-rays is the most widely used medical imaging modality for the detection of pathologies, the monitoring of their evolution and during certain surgical procedures. The objective of this thesis is to study a new semiconductor material based on perovskites for direct X-ray detection. A thesis is running since October 2022 at CEA on the development […] >>
