PhD Position - Scanning tunneling study of exotic superconductivity

Open positions are available in the quantum nanoscience department of the Peter Grünberg Institute, PGI-3 https://www.fz-juelich.de/de/pgi/pgi-3 and have the goal to advance the material basis for topological quantum computing. Funding is supported by the German Research Foundation (DFG). One-dimensional topological superconductivity is an exotic state of matter, which is not found in nature. However, this exotic quantum state is proposed to be realized in hybrid material systems, which combine nontrivial band topology with superconductivity, and has promising properties for potential applications in quantum computing. Our goal is to study hybrid topological insulator nanowires and flakes, to engineer nontrivial superconductivity via proximity effects and to study their properties using advanced scanning tunneling microscopy (STM).

Aufgaben

We look for excellent candidates who are interested in experimental work on superconductivity. Samples will be fabricated on site, with lithographic patterning performed at the Helmholtz Nanofacility (HNF), a state-of-the-art cleanroom, and studied in our scanning tunneling microscopes, at low temperatures and in magnetic fields. Your primary scientific tasks will be:

• Preparation of STM tips and samples, including cleanroom nanofabrication
• Conduction of experiments and data analysis
• Work in an international group environment
• Collaboration with internal and external project partners
• Preparation of scientific publications and presentations
• Participation in conferences in Germany and abroad
• Supervision of Master students (optional)

Profil

• Masters degree in Physics or Material Science, with excellent grades
• High degree of independence and commitment
• Analytic problem solving capabilities and creativity
• Reliable and thorough working style
• Experience in at least one of the following: Scanning probe microscopy, transport measurements, superconductivity
• Programming experience, for scripting and data analysis
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level. Knowledge of the German language is not mandatory but certainly appreciated
