Master Thesis: Stress Analysis in NV-Doped Diamond Using ODMR for Quantum Technologies

At the Fraunhofer Institute for Applied Solid State Physics we know our technologies like the back of our hand. Because we are one of the few scientific institutions worldwide to conduct research along the entire semiconductor value chain and on tailer-made synthetic diamonds. Whether high-frequency circuits for communications technology, voltage converter modules for electromobility, laser systems for measurement processes, or innovative hardware and software for quantum computers and quantum sensors: we develop tomorrow's technology in-house for a sustainable and secure society. When will you join us? In the field of quantum technology, the institute is working on the realization of a quantum computer based on color centers in diamond. We use nitrogen-vacancy (NV) centers as qubits, which are created during diamond growth via micorwave-assisted CVD, and characterized and controlled using in-house experimental set-ups. The purpose of this Master thesis opportunity is to establish and further develop a measurement and analysis chain for the quantative stress analysis NV-doped diamond by carrying out and evaluating ODMR measurements and linking them with suitable models in order to determine local stress components and inhomogeneities in diamond structures. The goal is to quantify stress as a quality and process parameter for the fabrication and optimization of diamond samples and structures for quantum technologies.
