Overview
4D STEM (Four-Dimensional Scanning Transmission Electron Microscopy) is an advanced characterization technique used to analyze the structural and crystallographic properties of materials at the nanoscale. The method records a diffraction pattern at every scan position of a focused electron beam, generating a four-dimensional dataset (2D real space + 2D reciprocal space).
This technique is widely used in materials science, nanotechnology, and semiconductor research to map strain, crystal orientation, phase distribution, and defects with high spatial resolution. 4D STEM enables detailed analysis of material structure beyond conventional electron microscopy.

Test Process
Sample Preparation
Thin specimens (electron-transparent, typically <100 nm thick) are prepared using techniques such as FIB or mechanical polishing.
1Beam Scanning
A focused electron beam is scanned across the sample in a raster pattern.
2Diffraction Data Collection
A diffraction pattern is recorded at each scan position using a fast pixelated detector.
3Data Recording & Evaluation
The 4D dataset is analyzed to extract structural, strain, and orientation information.
