The National Centre for High Resolution Electron Microscopy

The department’s research is aimed at:

• The realization of in-situ measurements combining structural investigations with for example electrical measurement or a gas atmosphere at elevated temperature in the transmission electron microscope,
• In-situ modification of materials at the nano scale,
• The analysis and understanding of the relation between the properties of crystalline materials and their structure, composition and morphology,
• Energy filtered transmission electron microscopy allowing the joint investigation of atomic arrangement, composition and electronic structure with 0.1 eV energy resolution.

In addition, the department provides facilities and service for electron microscopy investigations.
