PhD Student in 1D moiré physics
Our group focusses on the development of carbon-based (thermo)electric nanoscale devices and their application for quantum technologies and energy conversion. Our research is at the interface between fundamental quantum physics, thermodynamics, nanotechnology, and nanofabrication.
This project aims to harness the remarkable properties of 1D moiré systems to develop novel device architectures to advance our understanding of strongly correlated quantum systems. The central goal is to fabricate quantum devices hosting heterostructures of ultra-long graphene nanoribbons (GNRs) encapsulated in hexagonal boron nitride (h-BN). The charge transport properties of these devices will be investigated using a combination of conductance and thermocurrent spectroscopy in the presence of large magnetic fields and at cryogenic temperatures.
Your tasks
- Synthesis of graphene nanoribbons using chemical vapour deposition
- Nanofabrication of quantum devices in cleanroom
- Electric and thermoelectric characterization of devices at cryogenic temperatures and in the presence of large magnetic fields
- Presenting results at international conferences
- Dissemination of results in scientific journals
Your profile
We are looking for a highly-motivated student with a MSc degree in physics, quantum engineering, nanoscience, material science, electrical engineering or a related field. Excellent communication skills and fluency in English (both written and oral) are mandatory. Experience in the field of material synthesis, nanofabrication and/or quantum device characterization is highly appreciated. We are looking for committed and creative individuals able to work in a team. The candidate will work in a top-level research environment with state-of-the-art laboratory infrastructure, offering a unique opportunity to develop their research abilities.
Our offer
This fully-funded and full-time position will be available from September 2025 on, with a planned project duration of four years. The PhD student will develop expertise in the areas of material synthesis and characterisation, nanofabrication, (thermos)electric characterization of nanodevices at cryogenic temperatures, and carbon-based nanoelectronics.
We live a culture of inclusion and respect. We welcome all people who are interested in innovative, sustainable and meaningful activities - that's what counts.
