PhD on High Energy Laser Desorption Ionization for Chemical Imaging (HELDI)


Innovation in materials science is largely impacted by new abilities to characterize functional samples with the required detail and desirable simplicity. Spatially resolved microanalysis with lasers provides chemical information as a function of sample spot location, to probe micro-defects as well as the homogeneity in 3D. Time-resolved spectroscopy, as based on the spectral information probed with short laser pulses, permits operando characterization in snapshots. An ionization laser pulse and few nanoseconds in duration may thus directly map a material with unprecedented resolution, and permit a nano-scale, operando "chemical image" of any functional material.


Your tasks

  • Assemble and validate a setup for soft X-ray laser coupling to a spectrometer.
  • Carry out spatially resolved micro-analysis experiments on materials for the chemical imaging.
  • Develop quantification strategies data-fusing experimental signals.

Your skills (Requirements)


  • MSc in chemistry or electrical engineering with excellent grades in analytical methods.
  • Knowledge of vacuum and measurement methods, programming skills for data processing (eg. Matlab, R, python, etc).
  • Fluency in English is mandatory; skills in German are of advantage.

We are offering a multifaceted and challenging PhD position in a modern research environment with excellent infrastructure. The job is appointed at Empa and the PhD is awarded in Chemistry at the University of Zurich. Teaching assignments are expected for 300 hours. The position is available immediately and will remain open until filled.
