Project duration: 01.10.2014 – 30.09.2017
Correlative spatiotemporally resolved diffraction is able to gain fundamental and detailed understanding of the driving forces and processes of defect generation in crystalline materials during growth and processing. The methodology is based on the combination of in situ topography, diffraction laminography and further complementary methods. The evolution of cristals should be studied in dependence of thermal, mechanical, electrical and chemical load. The method will give new insights in materials sciences processes involved in wafer production, CMOS-technology or solar cells.
Key technologies developed in STROBOS-CODE are:
- Algebraic reconstruction methods for 3D diffraction imaging
- Correlation algorithms for topography and diffraction laminography
- High-speed streaming cameras
