PhD: Hard radiation detectors based on novel lead-free perovskite materials

100%, Zurich, fixed-term

A PhD position is available in the Functional Inorganic Material group (KovalenkoLab) at ETH Zurich (Department of Chemistry and Applied Biosciences). The research activities in Functional Inorganic Material group are focused on challenges related to the chemistry, physics, and applications of inorganic materials ranging from nanostructures to powders, thin films, and single crystals. Central to our efforts is the synthesis of new materials and their integration or self-assembly into multifunctional solid-state structures for various optoelectronic applications. Synthetic work, thorough materials characterization and innovative device fabrication are the cornerstones of our research.

Job description

The research activities involve the synthesis of new lead-free perovskite-based semiconductor single crystals, and further comprehensive characterization of their optoelectronic properties. The project will pave the way towards the development of a new generation of sensitive and cost-effective hard radiation detectors. Among other applications, such detectors would enable the widespread use of computed tomography medical imaging, currently highly demanded within the context of the COVID-19 pandemic. This research will be conducted in close collaboration with our industrial partner DECTRIS AG, a leading company in the field of X-ray and EM detection.

The application of state-of-the-art bulk fabrication methods (solution and solid-state crystal growth, PVD) will yield a variety of high-quality metal halide semiconductors, both thick films and bulk single crystals. The material optimization will be completed by means of advanced optical and electronic characterization methods including time-of-flight and other charge transport techniques. Pixelated detectors will be fabricated to test the suitability of these novel materials to serve as a basis for a new device generation. 

Your profile

  • Highly motivated candidates should have recently obtained a master degree in chemistry, material science with outstanding grades
  • Excellent knowledge of inorganic chemistry
  • Strong experimental background in materials synthesis, especially inorganic chemistry, with a basic knowledge of solid-state physics and electronics
  • Excellent communication skills and fluency in English (both written and oral) are mandatory
