Researcher in nanostructured X-ray scintillator detectors - Hiring in process/Finished, not possible to apply

The Division of Synchrotron Radiation Physics (www.sljus.lu.se) is a part of the Department of Physics and has more than 50 employees. The focus of the research is experimental studies of electronic, structural and chemical properties of materials, accelerators for Synchrotron radiation and instruments and methods for Synchrotron radiation. At the Division we use and develop a wide range of Synchrotron- and lab-based techniques, such as X-ray photoelectron spectroscopy/imaging and X-ray diffraction/imaging. We also host one of Sweden's largest facilities for scanning probe microscopy. We are additionally engaged in the development of the MAX IV Laboratory in the fields of beamlines, experimental stations, techniques for Synchrotron radiation and the accelerator systems.

Subject description
Scintillators convert X-ray photons into visible light, and form a critical part of X-ray detectors for clinical and industrial applications. Established bulk scintillators have limited spatial resolution, which limits the resolution in X-ray microscopy. This project will use nanofabrication methods to create novel scintillators that could overcome these limitations. Nanostructuring will be used to confine secondary electrons and photons, with the goal to create X-ray detectors with nanoscale spatial resolution.

Work duties
The main duty involved is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The postdoctoral fellow is expected to interact with the master students and the PhD students in the research group and contribute to meetings and seminars.

This project aims to create and study novel scintillators based on nanofabrication techniques. The work to be done will include synthesis, primarily in the Lund Nano Lab, and characterization in the new X-ray lab.

The work will be performed in collaboration with several other researchers at the institute as well as a number of Ph.D. students and master students.

Work duties include:

The main task is solution growth of metal halide perovskite nanostructures in AAO templates Morphological characterization using scanning electron microscopy Optical characterization using photoluminescence Structural characterization using X-ray diffraction Characterization of scintillator properties using a lab X-ray source. Analysis of the results Writing of publications Co-supervision of MSc and PhD students Collaboration and sample preparation for experts in advanced X-ray and optical methods.

Qualification requirements
Applicants must have:

• A PhD or equivalent research qualification within the subject of the position.
• Very good oral and written proficiency in English.
• It is required that the applicant has extensive experience with solution growth of metal halide perovskites, especially nanostructures of CsPbBr3.
• Experience in photoluminescence measurements and data analysis
• Experience in X-ray diffraction
• Experience in scanning electron microscopy
• Experience in writing publications.

Assessment criteria and other qualifications
Particular emphasis will be placed on research skills within the subject and on previous experience that helps to perform the described work duties within the short duration of the project.

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.
