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.

We are trying to keep our science going despite current limitations. Today Steffi presented her work on TMDs optics with only her at the @LPS_Orsay using our online teaching facility! She will present the same results soon at EMC2020 online 🙂
