Groupe d'études de la matière condensée (GÉMAC)

Laboratory presentation

GEMAC was born out of the fusion of 2 labs studying condensed matter physics : Laboratoire de Magnétisme et d'Optique de Versailles (LMOV) and Laboratoire de Physique des Solides et de Cristallogenèse (LPSC), which occurred in 2006. Nowadays, GEMAC is located on a single site in Versailles.
Its research activities are focusedon the physics and material science of materials such as large gap semiconductors, functional magnetic oxydes, molecular materials and the optics of nanometric systems. To make this research possible, GEMAC has advanced capabilities in thin film deposition, nano-objects and heterostructure synthesis.
