Humboldt-Universität zu Berlin - Abteilung Haushalt und Personal

Faculty of Mathematics and Natural Sciences - Department of Physics

The position is one of two positions within the sub-project "Linking structure and collective excitations of mol2Dmat heterostructures by fast electrons" within the Collaborative Research Centre 1772 "Heterostructures of Molecules and Two-Dimensional Materials" and focuses on the aspect of collective excitations. These excitations—such as superradiant states or various polaritons—are stimulated using an already implemented laser injection system in a transmission electron microscope (Nion HERMES). Electron energy-loss spectroscopy with an energy resolution better than 10 meV is employed to perform spectro-microscopy of photon-pumped systems with the high spatial resolution defined by the electrons. The scope of duties includes carrying out and evaluating these experiments, as well as, if necessary, preparing samples. Close collaboration with other sub-projects that produce, complementarily characterize, or model the material systems is fundamental to success. The possibility of obtaining a doctoral degree is given.

Job description:

• scientific service in research
• experiments on high-resolution spectro-microscopy of optically pumped states in systems of molecules and 2D materials in a modern transmission electron microscope (Nion HERMES) using a laser injection system
• tasks for your own scient. qualification (doctorate)

Requirements:

• completed Master’s degree in Physics
• proficiency in the fundamental skills of scientific work in physics:
  • good command of English, both spoken and written
  • structured and transparent handling of data and metadata (including laboratory records)
  • ability to familiarise oneself with new subject matter (including detailed literature research)
  • independence and ability to work in a team
• in addition, the following prior knowledge is desirable (in decreasing order of relevance):
  • (Transmission) electron microscopy and electron energy-loss spectroscopy
  • Python-based programming for data analysis and for control/automation of experiments
  • vibrational spectroscopy (e.g., infrared or Raman spectroscopy)
  • laser optics, in particular fibre lasers
