Cryo-EM

With broad expertise in advanced microstructural and chemical analyses by SEM/FIB/TEM, we are currently focussing on the preparation, handling and characterization of environmentally and beam-sensitive materials (2D-(semi)conductors, batteries, MOFs, polymers). Therefore, sophisticated techniques like cryo-EM, inert-gas/vacuum sample handling and low-kV/low-dose TEM are exploited. Students and collaborators are highly welcome!
