Based on the provided reference and common usage, "SA Ed" most likely stands for Selected Area Electron Diffraction.
Selected Area Electron Diffraction (SAED) Explained
Selected Area Electron Diffraction (SAED) is a crystallographic technique used within a Transmission Electron Microscope (TEM). It allows researchers to analyze the crystal structure of a specific, selected area of a sample.
-
How it works: In SAED, an aperture within the TEM column is used to select a specific region of the sample. The electron beam then diffracts off of this selected area, creating a diffraction pattern.
-
What it reveals: The resulting diffraction pattern provides information about the crystal structure, including:
- Crystal symmetry
- Lattice parameters
- Presence of defects
-
Applications: SAED is valuable in materials science, chemistry, and physics for:
- Identifying crystalline phases
- Determining crystal orientation
- Analyzing defects and grain boundaries
While "SA Ed" could theoretically stand for other things depending on the context, in the realm of materials science and microscopy, Selected Area Electron Diffraction is the most probable and common interpretation. Without further context, this is the most accurate full form.
