Joined PhD between STMicroelectronics (Crolles and Rousset), CEA LETI and IM2NP (AMU CNRS Marseille)
PhD subject: "Characterization and Modeling of Phase-Change Materials for Advanced Embedded Memory Applications."
Description: This PhD work will investigate in situ the structural change of these materials during heat treatment using various advanced X-ray scattering techniques (laboratory or synchrotron radiation facilities). These advanced experiments and their modeling by finite element-based methods will bring invaluable information on the physical mechanisms at work during crystallization (nucleation and growth of crystalline phases, stress development and relaxation...).
Aside from X-ray scattering additional input will be obtained from complementary techniques available from the partners (IM2NP/STM/CEA-LETI) involved in the PhD project such as transmission electron microscopy, Raman/FTIR/X-Ray Photoelectron spectroscopy, resistivity/reflectivity/ellipsometry vs temperature...). Thanks to the high penetrating power of x-rays dedicated deviceswill, in the longer term, be developed for operando real time investigations of memory cells during operations like set and reset at synchrotrons or XFELs.
Candidate profile: The ideal candidate holds a master’s 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 solid mechanics and programming skills will be appreciated.
