The Group for the Study of Condensed Matter (Groupe d'étude de la matière condensée, GEMaC) is a mixed unit of Versailles Saint-Quentin University (UVSQ) and the National Centre for Scientific Research (CNRS), and is part of the Institute of Physics (CNRS) and of the University Paris-Saclay. The research unit has been created in 2006 and is fully located on the science campus in Versailles since 2011.
Research in GEMaC is mainly experimental and concerns condensed matter physics, with in perspective applications for information storage and processing, and energy saving.
Various thematics are studied in GEMaC: diamond for electronics, semiconductor nanostructures based on zinc oxide, multifunctional magnetic oxides, phase transitions in molecular solids and quantum nanophotonics
Preparation of materials based on various epitaxial methods occur in a clean room, which is one of the main specificities of GEMaC, leading to realisation of thin layers, nanostructures and nanowires. Physical, structural, analytical, transport, magnetic and optical properties are investigated with various equipment, most of the time at the nanometer scale.
