Internship

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.
