4D scanning transmission electron microscopy (4D STEM) is a subset of scanning transmission electron microscopy (STEM) which utilizes a pixelated electron detector to capture a …

Explore 4D STEM technology from Gatan for advanced electron microscopy—ideal for high-resolution materials characterization.

Our research at UCI has focused on using 4D STEM to image the electronic properties of ferroelectrics, particularly the local electric field and charge distribution. A probe placed near to …

Jun 30, 2025 · Four-dimensional scanning transmission electron microscopy (4D STEM) is an advanced imaging technique providing a deeper understanding of materials at the atomic …

Conduct 4D STEM acquisition at speeds that exceed sample drift and/or damage. Matching the well-established STEM standard with a 10-µs dwell time is now possible.

Four-dimensional scanning transmission electron microscopy (4D-STEM) uses a fast, pixelated electron detector to collect far more information than a traditional STEM experiment. In 4D …

Jun 1, 2019 · The resulting datasets are 4D, hence the term 4D-STEM, by which we mean all forms of scattering measurements where 2D images of a STEM probe are recorded, either in …

In this work, we present an analysis of the information transfer in de-focused 4D-STEM, including additional coherent and incoherent scattering components that extend beyond the WPOA.

4D STEM involves acquiring a 2D convergent beam electron diffraction (CBED) pattern, at every pixel of a 2D STEM raster, generating a 4D dataset containing momentum and spatial …

These educational courses and hands-on sessions are designed to provide a comprehensive and practical understanding of 4D STEM, ranging from the fundamentals to advanced techniques …
