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

“Development of ultra-thin niobium nitride layers and 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, superconducting niobium nitride (NbN) plays a key role, as it is possible to deposit homogeneously ultra-thin layers of NbN by means of plasma-enhanced atomic layer deposition (PE-ALD).

Your Tasks:

• Methodical optimization of ultra-thin NbN films via PE-ALD
• Fabrication of micro-bridges and simple electronic circuitries
• Investigation of insitu passivation-coatings
• Determination of superconducting properties of NbN layers and micro-bridges at cryogenic temperatures
• Investigation of time-dependent stability of ultra-thin NbN films

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
