Systematic Errors of Electric Field Measurements in Ferroelectrics by Unit Cell Averaged Momentum Transfers in STEM

Achim Strauch et al.

Summary: When characterizing ferroelectric materials using the unit cell average of first moment data from 4D-STEM, various sources of systematic errors, such as acceleration voltage, STEM probe semi-convergence angle, sample thickness, and sample tilt out of zone axis, need to be considered. Simulations show that violation of point symmetry within the unit cells leads to systematic errors in calculated electric fields, which can exceed potential polarization-induced electric fields. These errors produce deflection gradients between different domains, but are mainly caused by dynamical scattering effects rather than the electric field itself.

Interference and interferometry in electron holography

Ken Harada

Summary: This paper reviews the basics of electron holography and discusses the general principles of holography and interferometry, as well as the unique physical phenomena of electron waves. It also examines the reconstruction of phase information from electron holograms. The upcoming papers in this special issue will focus on the application of electron holography in detail.

Aberration corrected STEM techniques to investigate polarization in ferroelectric domain walls and vortices

Kalani Moore et al.

Summary: Advancements in electron microscopy have allowed for the exploration of the complex nature of ferroelectric topological defects, observing changes in polarization, chemical composition, charge density, and strain. Current achievements include mapping the 3D nature of ferroelectric polar skyrmions and in situ biasing. The research focuses on understanding the fundamental physics and dynamics of domain wall and polar vortex formation in ferroelectrics.
