TEM

The transmission electron microscopy (TEM) research group is active in broad range of projects within the field of materials physics including nanoscale structural studies and their connection to macroscopic physical properties.

The TEM group has currently 10 PhD students, 3 post-docs and works in close collaboration with SINTEF through the TEM Gemini centre.

The group has for many years worked with SINTEF and Hydro on alloy development and nucleation of precipitates in aluminum alloys, including structure determination of metastable hardening phases by combining experiments (high resolution TEM, scanning TEM, quantitative diffraction and atom probe) and modeling (density functional theory).

In addition, there is a broad range of research activity on other materials, with a common emphasis on understanding of properties in relation nano/microstructure and on advanced microscopy techniques. Examples are:

• Multicrystalline silicon solar cell materialsdefects and impurity influence on efficiency.
• Electronic structure of thermoelectric and oxide materials.
• Functional perovskite materials: ferroelectric thin films and nanorods.
• Catalytic nanoparticles: electron tomography and in-situ TEM.
• High temperature corrosion in steels.
• Semiconductors nanowires for opto-electrical applications.
• Intermediate band solar cell materials.
• Aluminum surface properties related to corrosion.
• High quality TEM sample preparation: tripod polishing and FIB.
• Quantitative HAADF.
