Post-doctoral Offer - System for particle sensing with NEMS arrays for environmental and biomedical applications
Nano-Electro-Mechanical systems generate particular interest in a wide range of applications, from quantum measurements to biotechnology. In a highly competitive context of high-level research, CEA LETI MINATEC has been designing, modeling, fabricating and characterizing NEMS-based mass sensors for several years. The extremely low mass of those nanodevices allow them to reach unprecedented mass resolutions, of the order of 1 zg (10-21g). The very accurate measurement of a change in the NEMS resonance frequency upon particle accretion allows one to deduce the mass of the particle. The long term goal is to characterize biological particles in mass ranges currently unachievable by conventional techniques with possible applications in disease diagnosis, air quality control and characterization of novel therapeutic agents.

Postdoctoral Research Associate in Experimental Atomic Physics
Optically pumped magnetometers which monitor the magnetic resonance of macroscopic ensembles of atoms are currently the most accurate and precise sensors for magnetic fields. Our lab works on one of such magnetometers based on a thermal gas of helium-4 metastable atoms, a spin-one species. Our main achievement in last years has been the design and space qualification of the most recent generation of magnetometers available for spatial exploration, which were launched by ESA Swarm mission. Magneto-optical effects which are harnessed in these magnetometers could be also used for building new kinds of ultra-precise sensors with address a broader range of applications. We are looking for a motivated postdoc candidate willing to explore these effects both for advancing their understanding and for developing new kinds of sensors which are foreseen in the lab.
