Convergent-Beam Electron Diffraction: A Review of Techniques and Applications

A review paper by Michiyoshi Tanaka of Tohoku University on the convergent-beam electron diffraction (CBED) technique. The paper describes methods for point- and space-group determination in ordinary crystals, one-dimensionally incommensurate crystals, and quasicrystals. It also covers large-angle CBED for lattice defect and strain analysis, and briefly describes nanometer-scale structure refinement and charge density determination.

Use Cases

• Determining crystal point and space groups based on the described CBED symmetry analysis methods.
• Analyzing lattice defects and strain in materials like multilayer SiGe/Si based on the large-angle CBED technique.
• Refining nanometer-scale crystal structures using the CBED-based refinement method mentioned in the description.
• Determining crystal potential and charge density based on the CBED method briefly described.

Strengths

• Authored by a researcher from Tohoku University, a recognized institution in materials science.
• Provides concrete examples of analysis, such as for Sr₃Ru₂O₇ and multilayer Si₁-xGe(x)/Si materials.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
