ER-C 2.0: An update on plans for new electron microscopes at the Ernst Ruska-Centre in Forschungszentrum Jülich

This session will cover recent advancements of instrumentation for imaging and analytical purposes of transmission electron microscopy (TEM and STEM). Part of this session will focus on time-resolved electron microscopy and its various aspects to study optical excitations and nonequilibrium phenomena in materials. Contributions are welcome to describe the state of the art of instrumentation for high resolution imaging as well as all variants of analytical techniques.

IM 5: Quantitative image and diffraction data analysis

Structured illumination electron ptychography: probe design and experimental implementation

This session focusses on methods associated with different aspects of phase in electron microscopy. A first topic concerns mapping of the Coulomb potential, electric or magnetic fields, for instance using methods that retrieve the phase of the electron wave such as electron holography or focus variation reconstruction. The session also covers differential phase contrast (DPC) microscopy, which is based on the acquisition of a Ronchigram per scan position (4D-STEM) with a segmented, pixelated or other dedicated detector, using the first moment of the intensity distribution or a ptychographic reconstruction of the object phase. Another topic is related to the shaping of the phase of the electron wave using different kinds of phase plates, vortex beams, and beam shaping in general. Contributions may also tackle related theoretical topics, image simulation, influence of inelastic contributions and similar aspects.

MS 4: Functional thin films

This session focuses on the development and application of advanced imaging, diffraction and spectroscopy to provide new insight into the structural, compositional and functional properties of low-dimensional and quantum materials. A specific focus will be placed on methods for imaging individual defects, enhancing the contrast of light atoms, preparing and cleaning ultra-thin samples, developing automated workflows for low dose imaging of beam sensitive materials and linking electron microscopy with complementary characterisation techniques. Other topics of interest include in situ experiments carried out at cryogenic or elevated temperature, as well as in the presence of external stimuli such as applied voltage, field, gases or light.
