• Postdoc position at IM2NP (AMU CNRS Marseille), France

    Subject: "Nanostructure and crystallization mechanisms in Phase-Change Materials for Advanced Embedded Memory Applications"

    General aim:

    This work aims to study finely the optimized chalcogenides (typically GST) integrated in memory cells through original experiments to follow in situ the crystallization of thin films and the nanostructures of PCM in both amorphous and crystalline states.

    The evolution of stress and microstructure will be studied in thin films and then in patterned structures. In situ measurements of curvature and X-ray diffraction will thus be carried out in the laboratory and on a synchrotron beamline. And a reflection will be undertaken to carry out operando diffraction measurements on dedicated structures. It will be a matter of measuring, by time-resolved diffraction, the crystallization of a memory cell during cycling. This work will be performed in strong partnership with STMicroelectronics.


    The ideal candidate holds a PhD degree in Material Sciences (or equivalent), has a solid background in physics, good communication skills and is proficient in written and spoken English. Knowledge of x-ray scattering (and possibly previous experience with synchrotron radiation)and programming skills will be highly appreciated.
