Our research
The STEM group at the Laboratoire de Physique des Solides explores nano to atomic scale physics with ultra-high energy resolution electron spectroscopy
Our equipment
We are equiped with state of the art electron spectro microscopes fitted with various home-made cutting edge developments permitting original EELS, cathodoluminescence, PINEM or 4D microscopy modes.
Our networks
We are part of several french and european networks and projects.
