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. 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.

The abalone reveals its secrets about the origin of its shell
Many multicellular animals secrete a mineralized skeleton, a composite material in which the mineral phase, carbonated, phosphated or siliceous, is predominant. It is generally accepted that carbonates, which are abundant …
