This PhD position in Quantum Nanoscience at Delft University of Technology offers the opportunity to join the vanderZant lab, a world-leading research group at the forefront of quantum charge transport studies in biological nanowires. The project addresses the global challenge of e-waste by exploring non-toxic, biodegradable electronics, focusing on the remarkable discovery that certain bacteria (cable bacteria) can conduct electricity over centimeter distances with conductivities surpassing many man-made organic semiconductors. As a PhD student, you will fabricate electronic circuits using bio-nanowires, measure their electronic properties, and investigate quantum transport phenomena, including phase coherence and quantum nuclear tunneling, particularly at low temperatures. The research involves device fabrication in the Kavli Nanolaboratory's state-of-the-art cleanroom, advanced electrical measurements under varying conditions, and the interpretation and modeling of experimental results. You will work closely with a diverse team of academic staff, PhD students, and postdocs, and collaborate with biologists in Belgium who supply the cable bacteria. The position offers comprehensive training and support, fostering both scientific and personal development. The Faculty of Applied Sciences at TU Delft is a vibrant ecosystem focused on key enabling technologies such as quantum and nanotechnology, photonics, biotechnology, and materials for energy storage and conversion. The university is committed to diversity, innovation, and global impact. Employment conditions include a 4-year contract (initial 1.5 years with a go/no-go assessment, followed by 2.5 years upon satisfactory progress), a competitive salary (€3059–€3881/month), holiday and end-of-year bonuses, and a range of benefits including relocation support and flexible work arrangements. Applicants should have a Master’s degree in Physics or Nanophysics, strong interest in quantum transport, recommended experience in cleanroom fabrication and electrical measurements, proficiency in Python, and excellent English skills. The application deadline is December 1, 2025. Apply online with a CV and cover letter; applications by email or post are not accepted. The position is open from January 1, 2026.
