Claribel Dominguez

Claribel Dominguez is a Researcher in the Department of Physics at the University of Geneva (UNIGE), affiliated with Prof. Jean-Marc Triscone's research group. Her work focuses on understanding electronic and structural properties of nickelate-based heterostructures, particularly exploring metal-insulator transitions, interfacial couplings, and emergent phenomena in oxide superlattices. She received the UNIGE Subside tremplin award in 2021 to support her research on nickelate superlattices, which revealed novel coupling mechanisms between nickelates with distinct metal-insulator transition temperatures.

Her research integrates advanced materials synthesis (e.g., topochemical reduction, epitaxial growth) with cutting-edge characterization techniques including scanning transmission electron microscopy (STEM), X-ray diffraction, and optical spectroscopy. Key contributions include mapping orthorhombic domain structures, analyzing spin disproportionation effects, and probing electrically induced phase transitions at the atomic scale. These studies aim to bridge fundamental physics with potential applications in next-generation electronic devices.
