Abstract:
Defects are flaws in the crystal structure of semiconductors. These flaws can be missing atoms, or an atom sitting in the wrong place in the crystal. Such defects are interesting because they can change how a semiconductor material conducts electricity or absorbs and emits light. My defect research has two points of view. The first is how we can identify and control defects to remove them from the material, and thus improve the quality of diodes and transistors for power electronics. The second angle, and the topic of this talk, is how to use point defects in semiconductors for quantum technology (QT) applications. Certain point defects can be used as building blocks for QT. In this presentation, I will give some highlights of recent research projects that rely on the combination of theory and experiment.
Biography:
Marianne Etzelmüller Bathen received her M.Sc. degree in nanotechnology from the Norwegian University of Science and Technology (NTNU) in 2016, and was awarded a Ph.D. in physics from the University of Oslo (UiO) in 2020. She was a postdoctoral researcher at ETH Zürich from 2021-2023, and has since moved back to Norway to become Associate Professor in Semiconductor physics and quantum technology at UiO. In her research, she combines density functional theory calculations with electro-optical measurements and semiconductor device fabrication to exploit semiconductor point defects for quantum technologies.
Cake and coffee/tea is served from 12.00 to 12.15. The talk starts shortly after.
