PhD student in Conductive wood

Updated: 1 day ago
Deadline: 25 Nov 2022

Skilled and committed employees are a crucial factor in the success of Linköping University. And we need more of them. Our core expertise comes from teachers and researchers, but a successful university requires experienced and motivated employees in many fields. Everyone is important. We need to recruit many new employees thanks to, among all, an expansion in our research activity. We need you here. We look forward to receiving your application!

At the Department of Science and Technology, at the university’s Norrköping campus, we provide education and conduct research in physics and electronics, communications/logistics and media- and information technology. The department is recognised for its work in fields including logistics, visualisation and organic electronics. We combine academic excellence with fruitful collaboration with the Community.

Wallenberg Wood Science Center (WWSC) is a research center striving for scientific excellence with a focus on new materials from trees. The center creates knowledge and builds competence for an innovative and sustainable future value creation from forest raw materials. WWSC is a multidisciplinary collaboration between KTH, Chalmers, and Linköping University. The base is a donation from Knut and Alice Wallenberg Foundation, and the forest industry is supporting WWSC via the national platform Treesearch.

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

Your work assignments and workplace

Ionically and electrically conductive wood can be formed by letting conducting polymers diffuse into pretreated wood and used in supercapacitors and transistors. The concept of conductive wood is interesting from a sustainability perspective due to the potential for reduced processing compared to devices based on cellulose or CNF. Further development and improvement require a deeper understanding of the molecular mechanisms and interfaces. Therefore, the PhD student will pursue investigations with these main objectives: (i) Improved nanoscale understanding of the interaction between wood (cellulose, lignin, hemicellulose) and conductive polymers with emphasis on polythiophenes; (ii) Understanding of the conditions under which conductive polymer precursors will polymerize within wood samples; (iii) Wood pretreatment procedures that will improve the formation and/or the diffusion of conductive polymers in wood; (iv) Improved electrical conductivity and long-term stability of conductive wood. The work will include design/preparation of conductive wood samples and characterization with special emphasis on molecular interfaces and interactions, using methods such as e.g. SEM, X-ray scattering, FTIR, XPS, scanning probe techniques, as well as electrical and electrochemical characterization of macroscopic properties.

The PhD student will be part of a graduate school within the Wallenberg Wood Science Center (WWSC), which is a research center striving for scientific excellence with a focus on new materials from trees. The center creates knowledge and builds competence for an innovative and sustainable future value creation from forest raw materials. WWSC is a multidisciplinary collaboration between KTH, Chalmers, and Linköping University.

The PhD student will work in the Printed and Paper Electronics group, headed by Associate Prof. Isak Engquist, at the Laboratory of Organic Electronics (LOE). Within the Printed and Paper Electronics group we develop printed materials, components and circuits. Areas of special interest are energy storage in supercapacitors, electrically conductive wood and paper, and paper-based substrates for electrocatalysis. Many of our projects are based on national and international collaborations including a variety of competences. Read more at:

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 twelve units, each led by a principal investigator. Read more at

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
You have graduated at Master’s level in materials science, material chemistry, engineering biology, applied physics, or a related field or completed courses with a minimum of 240 credits, at least 60 of which must be in advanced courses. Alternatively, you have gained essentially corresponding knowledge in another way.

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 Doctoral studies at Linköping University

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

Winter 2022/2023 or by agreement.

Salary and employment benefits
The salary of doctoral students is determined according to a locally negotiated salary progression.

More information about employment benefits at Linköping University is available here.
