Offer Description

The growing demand for X-ray imaging requires sensitive X-ray detectors that allow the use of lower operational X-ray doses to decrease radiation-related health risks. Metal halide perovskites are semiconductor materials with outstanding optoelectronic properties, such as strong optical absorption over a broad energy range and favorable charge transport. These features turn them into excellent candidates for application in devices such as solar cells, light-emitting diodes, sensors, and (X-ray) photodetectors. However, the intrinsic instability induced by unwanted crystal defects in popular lead-based perovskites induce a rapid decrease in their performance and stability, and hinder their large-scale device application. In this PhD, the focus is to rationally develop and process highly crystalline, X-ray sensitive lead-free perovskite materials through micromanaging their electronic structure by composition and dimensionality engineering. Tailoring their optoelectronic performance and stability will be guided by applying an arsenal of characterization techniques and spectroscopy platforms for the careful assessment of the structural and photophysical properties. Newly developed compounds with enhanced stability will be integrated into X-ray detector devices, which will be validated and fine-tuned with the final goal to allow low-dose X-ray imaging.

Benefits

Funding is available for a 4-year PhD Research position, allowing you to focus on the research without the added pressure of securing external funding. Here are the specifics of the offer:
- Position Details: The position will commence as soon as possible (summer 2024), depending on your availability and the eventual arranging of a residence permit. The initial appointment is for a one-year period, which will be extended in case of a positive evaluation based on research outcomes and performance.- Opportunities for Career Advancement: Opportunity to work on pioneering research in the field of optoelectronic materials with real-world applications. Chance to collaborate with leading experts in closely connected fields, providing an enriching experience and excellent networking opportunities.You will be encouraged to present your findings at national and international conferences, further enforcing your academic profile.As a PhD researcher, you’ll have the chance to mentor master thesis students, contributing to their academic development as well as honing your own supervisory skills.KU Leuven's vibrant academic community provides a supportive environment for research, with various interdisciplinary workshops, seminars, and courses to broaden your knowledge and skills.- Work Environment: You will be joining a diverse, multidisciplinary team that values collaborative research. You will have access to state-of-the-art research facilities, including cutting-edge synthesis facilities and spectroscopic instruments.

Eligibility criteria

The candidate not only demonstrates academic excellence but also possesses qualities of innovative thinking, a collaborative spirit, and enthusiasm and dedication to the project. Specifically, the candidate should fulfill (most of) the following criteria:
- Educational Background: Hold a Master in Science in a relevant field, such as (Physical) Chemistry, Materials Science, or Nanoscience, with a focus on materials chemistry and characterization. - Technical Expertise: Have hands-on experience in the synthesis and processing of perovskite (micro)crystals, perovskite films and/or hybrid structures (in glovebox). Proficiency in structural and optical characterization methods such as X-ray diffraction, (transient) absorption and (time-resolved) photoluminescence spectroscopy. Optoelectronic device engineering and characterization is considered a plus. - Interdisciplinary Collaboration: Openness and enthusiasm for interdisciplinary research that spans chemistry, physics, material science, and engineering. Ability to communicate effectively with scientists from various backgrounds, harness a multi-faceted approach to challenges.- Soft Skills: A proactive approach to solve problems, create independent thinking and acting, while being an effective team member. Good written and oral English communication skills, including the ability to prepare manuscripts for international peer-reviewed journals and present research findings at international conferences.- Adaptability: Willingness to adapt to new methodologies as the project evolves.
