About this position
This PhD project explores how optical metasurfaces can be used to control quantum electron wavepackets in an ultrafast electron microscopy setting. The work focuses on the interaction between high-energy electrons and extreme light fields inside a scanning electron microscope, using photon-induced near-field electron microscopy (PINEM) to study how confined optical near fields exchange energy with a pulsed electron beam.
You will develop specially designed non-local metasurfaces built from structured 2D dielectrics and nanometer-thin transition-metal dichalcogenide layers. These structures are intended to enhance and tune the electron-light coupling in an ultrafast SEM and to shape the electron wavepacket in space and time, with the goal of generating and controlling effects such as attosecond electron pulse trains.
The project combines theory, modelling, design, fabrication and advanced measurements. In the first phase, you will learn to operate the ultrafast SEM at AMOLF, study PINEM theory, and design and fabricate metasurfaces in the Amsterdam NanoCenter cleanroom. Later stages focus on integrating the metasurfaces with PINEM experiments, measuring the electron-light interaction, and tailoring electron wavepackets through coherent interactions. The final phase examines coherence-related effects, including correlations between electron energy loss and cathodoluminescence and a quantum-eraser geometry.
You will be based in the Photonic Materials group at AMOLF, led by Prof. Albert Polman, and work closely with the 2D Nanophotonics group at the University of Amsterdam, led by Dr. Jorik van de Groep. The project brings together expertise in ultrafast electron-light-matter interaction, cathodoluminescence, metasurface design, fabrication, and optical characterization in a highly collaborative research environment.
The position offers access to state-of-the-art ultrafast electron microscopy systems and shared nanofabrication facilities, with strong interaction across AMOLF and the University of Amsterdam.
