Microscopy Conference 2023

Quantitative electric field determination in semiconductor homo- and hetero-interfaces using electron diffraction and 4D-STEM

IM 6: Phase-related techniques & 4D STEM

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 1: Energy-related materials and catalysts

Establishing in-situ heating experiments of monolithic LiNiO2 particles in O2 atmosphere

The session is focused on generating insights into the function of materials for energy storage, energy conversion and catalysis. Topics can be – but are not restricted to - charge transport, dynamics at interfaces (electrolyte/electrode or gas-phase/catalyst surface), cycling behavior and aging/deactivation. We are very interested in contributions that attempt to capture the relevant functional state of energy materials and catalysts, i.e., studies that reach beyond imaging of isolated systems in vacuum or investigations that employ an embedded multi-scale (in space and time) approach that allows to link between atomistic and collective dynamics. We also call for contributions regarding efficient detection of various generated signals, correlative application of analytical methods, as well as utilizing and developing quantitative data-analysis and machine learning. Studies on the impact of the electron beam for (in-situ) investigation of materials for energy-related or catalysis applications are also highly welcome.
