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.

🔬⚡️❄️ Want to track #insitu metal/insulator transitions in a NION monochromated electron microscope ➡️ we’re recruiting now a #postdoc in the team @STEM_LPS within the ANR @AgenceRecherche IMPULSE project @LPS_Orsay @UnivParisSaclay @laura_bocher
➡️ http://equipes2.lps.u-psud.fr/stem/category/…

Interested in working on the best monochromated #ElectronMicroscopy and challenging it with #Synchrotron based spectroscopy? Check out our #PhD scholarship where such outstanding tools will be combined to investigate 2D electron gases at oxide interfaces! https://www.stem.lps.u-psud.fr/2d-gases-oxide-nanostructures-revealed-high-space-energy-and-momentum-resolved-spectroscopy

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 🙂
