PhD opportunity in Physics at Lund University on nanoscale X-ray diffraction for ferroelectric domain dynamics . The project sits at the intersection of materials physics , synchrotron science , and instrumentation development , with experiments centered on the NanoMAX beamline at MAX IV . The doctoral student will develop advanced XRD methods to image and study how domains evolve and switch in ferroelectric materials. The research is highly relevant to future technologies such as memory, computing, and functional devices. The work includes designing and testing a new system for electrical measurements and heating at NanoMAX, performing synchrotron experiments at MAX IV and other international facilities, and analyzing large datasets using AI and computational clusters. The position is embedded in a strong international collaboration network involving NanoLund , the Division of Synchrotron Radiation Research , NanoMAX at MAX IV , Max Born Institute in Berlin, and the University of Mainz . Applicants with experience or interest in nanofocusing and coherent X-ray methods , X-ray techniques and analysis , programming and data analysis , and ferroelectric/ferromagnetic/ferroic materials are especially encouraged to apply. Eligibility requires a relevant second-cycle degree or equivalent, plus a relevant independent work/degree project of at least 30 higher education credits for Physics. Strong English skills, independence, collaboration, and research initiative are important. The employment is full time for 4 years, with up to 20% teaching or departmental duties extending the appointment accordingly. Application deadline: 31 July 2026 . Apply in English via the linked portal and include a CV, personal letter, degree certificates, and any additional supporting documents.
