Dominique Juncker (born 12 April 1958) is a French physicist and materials scientist noted for pioneering work on oxide perovskite heterostructures, epitaxial thin films, and correlated-electron interfaces. Juncker held positions at the Centre National de la Recherche Scientifique and academic appointments at the Université Clermont Auvergne and the École Normale Supérieure (Paris), and collaborated with laboratories such as the Max Planck Society and Lawrence Berkeley National Laboratory.

Early life and education

Juncker was born in Lyon and educated at the Lycée Louis-le-Grand before entering the École Normale Supérieure (Paris). He completed a doctorate at the University of Lyon under advisors associated with the Commissariat à l'énergie atomique et aux énergies alternatives and trained in experimental techniques developed at the Institut Laue–Langevin and the European Synchrotron Radiation Facility. His graduate work intersected with groups at the Massachusetts Institute of Technology, the University of Cambridge, and the ETH Zurich.

Juncker began his career at the Centre National de la Recherche Scientifique where he led teams in thin-film deposition linked to the Pierre and Marie Curie University (Paris 6). He established collaborative programs with the Max Planck Institute for Solid State Research, the Oak Ridge National Laboratory, and the National Institute of Standards and Technology. Juncker served as visiting professor at the University of California, Berkeley and as guest researcher at the Paul Scherrer Institute. He directed a joint unit with the Sorbonne University focused on oxide electronics and held advisory roles with the European Research Council and the French Ministry of Higher Education and Research.

Juncker's research advanced understanding of interface-driven phenomena in complex oxides, building on concepts from the Hubbard model and the study of high-temperature superconductivity associated with materials like YBa2Cu3O7. He developed epitaxial growth protocols using pulsed laser deposition and molecular beam epitaxy that influenced work at the National Renewable Energy Laboratory and informed studies at the IBM Watson Research Center. His teams reported emergent two-dimensional electron gas behavior at oxide interfaces similar to phenomena explored in LaAlO3/SrTiO3 systems and connected to research on graphene and topological insulators such as Bi2Se3. Juncker contributed to measurements using techniques from the Rutherford Appleton Laboratory and the Paul Scherrer Institute, including angle-resolved photoemission spectroscopy methods employed at facilities like the Advanced Light Source and the Diamond Light Source.

He published on strain-engineered magnetism and multiferroicity in perovskites, relating to work by researchers at the University of Oxford and the California Institute of Technology. Juncker's group characterized oxygen vacancy dynamics with in situ electron microscopy methods developed alongside teams at the Max Planck Institute for Intelligent Systems and correlated their findings with transport phenomena studied at the Argonne National Laboratory. His interdisciplinary collaborations connected to topics explored by the Royal Society, the Deutsche Forschungsgemeinschaft, and the Japan Society for the Promotion of Science.

Juncker's recognitions include the CNRS Silver Medal and the Wolf Prize in Physics for contributions to oxide interface physics, alongside election to the Academy of Sciences (France) and fellowship in the European Physical Society. He received visiting fellowships from the Alexander von Humboldt Foundation and the Fulbright Program, and was awarded honors by the Institut Universitaire de France and the European Research Council for advanced grants supporting oxide electronics. National honors included orders issued by the Legion of Honour-related institutions.

Juncker is associated with mentoring a generation of scientists who took positions at the University of Illinois Urbana–Champaign, Seoul National University, and the University of Tokyo. His legacy is reflected in continued research at institutions such as the Massachusetts Institute of Technology, the Stanford University, and the University of Cambridge where oxide heterostructures remain an active field. Juncker's approaches influenced industrial research at companies including Intel, Samsung Electronics, and Toyota Motor Corporation in areas overlapping with oxide electronics and energy materials. He is married and has collaborated on outreach initiatives with the CERN and the UNESCO science programs.
