General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Internship
Job title
Reproducible elemental quantification of technological materials by photoemission H/F
Subject
The development of advanced electronic components requires a thorough understanding of the elemental composition of the constituent thin-film materials at the micro- and nanometer scale. This internship focuses on the physical aspects of X-ray photoemission to gain better understanding about reproducible quantification with uncertainties of 5% and below.
Contract duration (months)
6
Job description
Among the analytical techniques available in cleanrooms and laboratories, hard X-ray photoemission spectroscopy (HAXPES) is gaining ground due to its ability to perform non-destructive measurements below the surface and deeper at the sub-surface to adress buried layers. This internship addresses the major challenge, within the international community in the field, of high-precision quantification in HAXPES, based on recent methodologies using both intensity calibration with a spectrometer transmission function and core-line intensity determination using Tougaard background substraction. The internship will focus on refining the intensity determination by incorporating physical data describing the energy losses of photoelectrons in the materials under investigation.
Methods / Means
Hard X-ray photoemission spectrometer/dedicated quantification softwares
Applicant Profile
Master 2 Materials Science, Condensed Matter Physics or equivalent. An interest in carrying out physical measurements on ultra-high-vacuum systems (either commercial or home-made ones), analysing spectroscopic data using dedicated software, and working as part of a team within a multi-partner collaboration involving an academic laboratory (the Paris Institute of Nanosciences) and a British standards institute (the National Physical Laboratory).
