Faculty of Science Master's 38 hours 15182 €3,059 - €3,881 Closes on: 30-07-2026 Join us! Follow electrons in quantum materials in real time! Do you see yourself pushing the envelope with a next-generation Ultrafast Transmission Electron Microscope (UTEM) to directly image physical processes happening on insanely short timescales? The optics of quantum materials group is looking for an enthusiastic PhD candidate to join a cutting-edge experimental physics project at the interface of ultrafast science and quantum materials. This is an opportunity to do science that has simply never been possible before. Modern electron microscopes can map materials with sub-Ångstrom spatial resolution and, in combination with an energy analyser, detect fundamental excitations of quantum materials using Electron Energy Loss Spectroscopy (EELS). Most measurements yield a static or time-averaged picture, while the non-equilibrium dynamics that govern heat transport, charge flow, and phase transitions unfold on femtosecond (10⁻¹⁵ s) timescales. Ultrafast TEM addresses this gap by combining femtosecond laser pulses with pulsed electron probes in a pump–probe scheme: a laser pulse triggers a physical process, and a precisely timed electron pulse images or spectroscopically probes the material a controlled time delay later. This NWO funded project, carried out in collaboration with Thermo Fisher Scientific and Doctor X works B.V., will push this technique to its limits through novel microwave cavity technology — achieving few-femtosecond temporal resolution in imaging mode, and few-tens-of-meV energy resolution in ultrafast EELS mode. As a PhD candidate focusing on the scientific program, you will exploit these new capabilities to tackle two outstanding problems in condensed matter physics: Memristive switching dynamics: HfO₂-based memristive devices are among the most promising candidates for neuromorphic computing, yet the microscopic mechanism of resistive switching — believed to involve the nucleation and growth of conducting filaments — remains poorly understood and difficult to control. You will use spatially resolved, time-resolved electron microscopy to directly image filament formation in real time with nanometre precision, providing the first direct experimental window into this process. Strange metal dynamics: The "strange metal" phase of the high-temperature superconductor Bi₂Sr₂CuO₆ exhibits anomalous properties that challenge conventional theoretical models. Using ultrafast EELS, you will probe the dynamics of these fluctuations and compare the outcomes with measurements of the (static) optical conductivity. All about this vacancy This is what you will do You will work in close collaboration with the group of Prof. Dr. Jom Luiten at the TU/e where you will work in tandem with a second PhD student responsible for the instrument development. At the start of the project you will familiarize yourself with the instrument at TU/e and the experimental techniques. You will then prepare various samples for TEM or EELS experiments.
