Colored X-ray spectroscopy dedicated to ultrathin inorganic materials H/F

Description de l'offre : The characterization of nanometric layers developed for advanced CMOS devices (gate-metal stack) and other innovative materials (transition metal dichalcogenides) is based in particular on state-of-the-art X-ray spectroscopy equipments (fluorescence, photoemission). Such tools combine multi-energy excitation and angle-resolved analysis to optimize sensitivity to ultrathin materials. The objective of the internship is the development of quantitative analysis protocols by multi-energy angular analysis. The work required: will be carried out in a multidisciplinary international context (interaction with the characterization and process teams, collaboration with a Japanese equipment manufacturer) will be balanced between experience (50%) and simulation (50%) This 6-month internship will mainly focus on fluorescence analysis. It may be followed by a PhD contract which will extend the field of interest to the combination multi-energy and angle-resolved X-ray photoemission and fluorescence analyses.
