Simulation, fabrication and characterization of transparent piezoelectric transducers based on ZnO nanowires Detailed Topic Piezoelectric devices are attracting growing interest as a micro-source of energy by harvesting mechanical ambient energy, and as sensors via the direct piezoelectric effect. In this context, semiconducting materials in the form of nanowires constitute a promising building block for the […] >>

Quantum computing is nowadays a strong field of research at CEA-LETI and in numerous institutes and companies around the world. In particular, RF magnetic fields allow to control the spin of silicon qubits, and pathway for large scale control is a real technological challenge. The bibliographic analysis and the studies already carried out will able […] >>

Narrowband (NB) radio signals are widely used in the context of low power, wide area (LPWA) networks, which are one of the key components of the Internet-of-Things (NB-IoT). However, because of their limited bandwidth, such signals are not well suited for accurate localization, especially when used in a complex environment like high buildings areas or […] >>

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 […] >>

The overall objective of the project is to propose a new mode of biocatalytic production based on continuous flow and combining macro and micro-fluidics. The aim is to develop a biocatalysis process involving fluidic bioreactors capable of ensuring continuous biotransformation, thanks to immobilized enzymes or whole cell catalysts. This process will be optimized to improve […] >>
