We are looking for a PhD student in Applied Physics, formally based at the Department of Science and Technology, Campus Norrköping.

This recruitment is connected to the Wallenberg Initiative Materials Science for Sustainability (WISE, wise-materials.org ). WISE, funded by the Knut and Alice Wallenberg Foundation, is the largest-ever investment in materials science in Sweden and will encompass major efforts at Sweden’s foremost universities over the course of 10 years. The vision is a sustainable future through materials science. Read more: https://wise-materials.org

Your work assignments and workplace
A major opportunity for saving energy is to transition from cooling houses (≈ 3 kW) and vehicles, to cooling of individuals (≈ 0.1 kW) through active wearable coolers. The PhD student will work towards this goal by developing novel stretchable conductors and devices for wearable thermoelectric cooling. The main objectives are to develop: i) High-power stretchable conductors based on kirigami structures and stretchable conducting composites. ii) Methods for simulating and generating optimized device designs. iii) Fabrication processes for materials and devices, including laser ablation and printing. iv) Wearable cooling panels for integration in textiles. The PhD studies will include design and processing of materials and components, together with characterization of electrical, mechanical and thermal material properties and device performance.

The PhD student will work in the Soft Electronics group, headed by Senior Associate Prof. Klas Tybrandt, at the Laboratory of Organic Electronics (LOE). Within the Soft Electronics group we develop composite materials, design concepts and devices for soft and deformable electronic systems. Areas of special interest are stretchable (semi)conductors, wearables, energy harvesting/storage, and neural interface technologies. Many of our projects are based on national and international collaborations including a variety of competences. Read more at: www.liu.se/soft-electronics

At the Laboratory of Organic Electronics (LOE) we explore electronic and optical properties of organic semiconductors, biomaterials from the forest, and hybrid organic materials. Our activities span the range from basic research to commercialization, the latter carried out in close collaboration with the institute RISE. LOE currently has ~140 researchers and research students divided into 11 groups, each led by a principal investigator. Read more at www.liu.se/loe

All early-stage researchers recruited into the WISE program will be a part of the WISE Graduate School (https://wise-materials.org/research/graduate-school/ ), an ambitious nationwide program of seminars, courses, research visits, and other activities to promote a strong multi-disciplinary and international network between PhD students, postdocs, researchers, and industry.

As a doctoral 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% of full-time.

Your qualifications
A suitable background for this position is in materials science, mechanical engineering, electrical engineering, applied physics, or a related field. You have graduated at Master’s level or completed courses with a minimum of 240 credits, at least 60 of which must be in advanced courses.

Desirable personal skills and traits for the position are highly motivated, ambitious, problem solving skills and teamwork ability. Research at LOE is carried out predominantly in English, so relative fluency is favorable. Great emphasis will be placed on personal qualities and suitability.

Terms of 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.

The employment has a duration of four years’ full-time equivalent. You will initially be employed for a period of one year. The employment will subsequently be renewed for periods of maximum duration two years, depending on your progress through the study plan. The employment may be extended up to a maximum of five years, based on the amount of teaching and departmental duties you have carried out. Further extensions can be granted in special circumstances.

Starting date
Summer/fall 2023 or by agreement.

Salary and employment benefits
The salary of PhD students is determined according to a locally negotiated salary progression. The starting salary for a PhD at ITN is 31 500 SEK/month (fulltime).
