Joel Davidsson

Joel Davidsson is an Assistant Professor at Linköping University's Department of Physics, Chemistry and Biology (IFM), within the Theoretical Physics (TEOFY) division. His research focuses on identifying and characterizing point defects in semiconductors for quantum technologies, leveraging high-throughput computational methods. He leads the ADAQ Database Initiative, which provides open-access data on defect properties via automated workflows.

Davidsson holds a Master's (2015) and PhD (2021) from Linköping University, specializing in orbital-free density-functional theory and quantum materials. His work emphasizes accelerating the discovery of defects suitable for quantum computing, single-photon emitters, and hybrid quantum systems.

His research integrates

• First-principles calculations (DFT)
• Automated defect analysis (ADAQ platform)
• High-throughput screening of semiconductor defects

Key projects include NV-like defect exploration in oxides and SiC, and developing symmetry analysis tools for defect orbitals.

Collaborations involve teams at the University of Edinburgh and supercomputing facilities. His group includes PhD student William Stenlund and contributes to grants from WASP-WISE for sustainable materials research.

Notable achievements include predicting MgO spin qubits, discovering telecom-wavelength emitters in 4H-SiC, and advancing defect database interoperability through initiatives like OMDI 2021.
