Microscopy Conference 2023

Can we enhance the depth of focus/depth resolution in STEM with an electrostatic phase plate?

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.

Poster

This symposium is hosted by the DGE Young Microscopists working group (yDGE) and will cover topics especially interesting for young researchers. For this, we invited experts who will give insights on publication writing and career planning.
In addition, we want to offer students the opportunity to give a short talk on their work in front of their young colleagues, to gain presentation experience in a casual atmosphere and enhance the scientific exchange.
The newly founded working group DGE Young Microscopists will briefly introduce their activities and possibilities to join.
Our goal is a lively, relaxed exchange between students and early-career postdocs to connect to like-minded colleagues. For this, the symposium will be followed by a social event nearby the conference's venue.


DGE young microscopists symposium

Evaluation a 48 pixel programmable phase plate for electron wavefront shaping

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.
