The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science.
The PTB in Berlin-Adlershof uses synchrotron radiation from the electronen storage rings Metrology Light Source (MLS) and BESSY II for metrology at own beamlines. The progressing miniturization, especially in semiconductor fabrication, presents new challenges for metrology. For the further development of appropriate measuring techniques, Department 7.2 "X-ray measurement technology with synchrotron radiation" of Division 7 is looking for a doctoral candidate, specializing in physics, applied mathematics or a relevant engineering science to join us as soon as possible. The position is available on the basis of a 3-year fixed-term contract. The renumeration will be in accordance with renumeration group 13 TVöD Bund (85 %). You will be employed at our Berlin-Adlershof site.
Doctoral candidate, specializing in physics, applied mathematics or a relevant engineering science
Focus: Characterization of nanomaterials with the help of X-ray spectrometry under grazing incidence or grazing detection
Grazing incidence or grazing exit X-ray fluorescence (GIXRF / GEXRF) is used at PTB to characterize different nanostructures, from simple layers to three-dimensional structures. PTB's own measurement setups enable dimensional characterization and traceable quantification of the different elements present in a sample. These measuring principles are to be further developed especially for state-of-the-art applications in the semiconductor industry.
Independent conception, execution and data evaluation of X-ray spectrometric experiments
