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