Coherent electron diffraction imaging

We are developing coherent electron imaging techniques that capture 3D atomic arrangement information via relative phase shifts of the scattered electron waves.

When using coherent probing waves, the phase differences due to 3D positions of individual scatterers within a 3D sample are captured in an interference pattern, diffraction pattern or hologram. It is then a numerical task to recover the missing phases, and with this, the positions of individual scatterers within the sample. 


Our current research topics include: novel high-resolution 3D diffraction and imaging methods, iterative phase retrieval, coherent diffraction imaging, holography, convergent beam electron diffraction, 2D materials.
