PhD in In-situ Optical Sensing for Polymer-based Optoelectronics University of Twente in Netherlands

PhD opportunity at the University of Twente in the Department of Molecules and Materials / Faculty of Science & Technology (TNW) on in-situ optical sensing for polymer-based optoelectronics.

The project focuses on developing optical sensing techniques to observe how charge, structure, chemistry, morphology, and local electric fields evolve in conductive and functional polymer materials during operation. The research combines physics, chemistry, materials science, electrical engineering, and computer science, with hands-on work in optics, spectroscopy, UV-Vis, Raman, and surface-enhanced Raman spectroscopy. The goal is to enable energy-efficient organic-based optoelectronics, molecular memory, neuromorphic devices, and chemical sensing.

The PhD researcher will select and design conductive polymers, fabricate electronic devices, build an in-situ optical sensing platform, and model electrical and optical inputs/responses for energy-efficient computing as a proof of concept. The role is embedded in a collaborative, interdisciplinary environment with access to state-of-the-art facilities and nearby high-tech partners.

Eligibility highlights: a BSc or MSc in Physical Chemistry or Physics is required, with proven experimental skill in optics and spectroscopies. Applicants should be fluent in English, have good coding and analysis skills, be willing to develop modelling skills, and show interest in organic functional materials and polymer synthesis. Strong motivation, critical thinking, and teamwork are emphasized.

Funding and terms: 4-year PhD appointment; gross salary from €3,059/month in year 1 to €3,881/month in year 4; holiday allowance, year-end bonus, pension, relocation and immigration support, and professional development through Graduate School Twente.

Application deadline: 5 July 2026. Apply online with a CV, motivation letter, BSc/MSc transcripts, and at least one referee contact. An interview and scientific presentation are part of the selection process.
