Master Thesis in the Competence Center for Micro- and Nanotechnologies

The Leibniz Institute of Photonic Technology e.V. (Leibniz-IPHT) in Jena is a non-university research institution and is closely related to the Friedrich Schiller University Jena and a member of the Leibniz Association. The Competence Center for Micro- and Nanotechnologies at Leibniz-IPHT now offers the possibility for a

Master Thesis


“Fabrication of a ternary NbxTi1-xN layer stacks for superconducting quantum circuits”


The international prominent research in the fields of quantum computing and quantum metrology requires ultra-thin layers and structures made of materials, which have superior electrical properties at cryogenic temperatures. Here, disordered superconductors like NbxTi1-xN niobium nitride (NbN) show unique phenomena, but the fabrication is quite challenging. The goal of this work is therefore the fabrication of NbxTi1-xN using PE-ALD and its investigation in regard to the superconducting properties.


Your Tasks:

  • Fabrication of NbxTi1-xN layer stacks using PE-ALD
  • Structuring of micro-bridges and simple electronic circuitries
  • Determination of superconducting properties of NbxTi1-xN layers and micro-bridges at cryogenic temperatures

Your skills and expertise:

  • Bachelor`s degree in physics/material sciences (FH/Uni) or equivalent
  • Experimental skills and interest in working in cleanroom
  • The ability to work creatively and independently towards developing your own research project

We offer:

  • An interdisciplinary research within two groups/departments at Leibniz IPHT: Competence Center for Micro- and Nanotechnologies and Quantum Systems
  • Payment on basis of student assistant

Further information about scientific details of the project can be obtained from:

Dr. Mario Ziegler (, Tel: 03641-206539) or Dr. Sven Linzen (, Tel: 03641-206122).
