We are looking for a PhD student in flexible X-ray detectors.

Your work assignments

Flexible X-ray detectors represent a future technology that can benefit applications spanning several scientific, medical, and technological fields. Our joint project funded by the Knut and Alice Wallenberg foundation aims to realize flexible X-ray detectors by developing new organic semiconductors that can fulfil the critical requirements on flexibility, X-ray absorption, and charge transport simultaneously. You will focus on the development of X-ray detectors using new materials, assisted by advanced characterisations. You will be working jointly with chemists, materials scientists and device physicists to carry out your research, which will involve close and regular interaction with the other participating research groups at Linköping university (led by Prof. Mats Fahlman), Chalmers University (led by Prof. Eva Olsson) and Uppsala University (led by Prof. Sascha Ott).

As a PhD student, you devote most of your time to doctoral studies and the research projects of which you are part. Your work may also include teaching or other departmental duties, up to a maximum of 20 per cent of full-time.

Your qualifications

You have graduated at Master's level in Physics, Chemistry, Materials or a related field or completed courses with a minimum of 240 credits, at least 60 of which must be in advanced courses in Physics, Chemistry, Materials or a related field . Alternatively, you have gained essentially corresponding knowledge in another way.

Qualified candidates are expected to:

• Independently undertake the research activities
• Work collaboratively and openly as part of a team
• Act as a source of information and advice to other members of the group on scientific protocols and experimental techniques
• Take initiatives on research-related tasks
• Acquire new knowledge
• Have prior experimental experience of what is described in the job description above— especially that related to physics, and/or materials/device development.

Please include a Letter of Intent, specifying:

• why you want to do a PhD,
• why you are interested in this position, and
• why you believe that you are qualified for this position.

Your workplace

The group led by Prof. Feng Gao focuses on solution-processed optoelectronic devices, mainly based on semiconducting perovskites and organic semiconductors. The group is part of https://liu.se/en/organisation/liu/ifm/efm, where we develop photonic and electronic materials energy conversion and storage.

The employment

When taking up the post, you will be admitted to the program for doctoral studies. More information about the doctoral studies at each faculty is available at https://liu.se/en/research/doctoral-studies

The employment has a duration of normally four years' full-time equivalent. Extension of employment up to five years is based on the degree of teaching and institutional assignment. Further extensions may be granted in exceptional circumstances. You will initially be employed for one year, after which your employment will be renewed for a maximum of two years at a time, depending on your progress through the study plan.

Starting date by agreement.

Salary and employment benefits

The salary of PhD students is determined according to a locally negotiated salary progression.
