Welcome! Our lab uses electronic sensor spins in diamond to study spin and charge transport in condensed-matter systems, ranging from magnets to 2D materials and quantum devices.
The magnetic fields generated by spins and currents provide a unique window into condensed-matter physics. We study these fields at the nanoscale using the excellent sensitivity and broad temperature operability of the nitrogen-vacancy (NV) sensor spin in diamond. Please see this review in Nature Reviews Materials for background and our Research section.
Our experiments involve techniques such as (single-spin) magnetic resonance, (single-photon) photoluminescence microscopy, atomic-force microscopy, cryogenics, and microwave engineering.
We are located at Delft University of Technology, home to Nobel Laureates Jacobus Henricus van ‘t Hoff and Simon van der Meer, amongst many other great scientists. We are part of the Department of Quantum Nanoscience, as well as the Kavli Institute of Nanoscience.
We are looking for talented and passionate Master students and PhDs. You can find more information here! (more info)
We are grateful for funding from Delft University of Technology, NWO, the Frontiers in Nanoscience program, and the Kavli Foundation.
