Electron Diffraction Examples

Single crystal

Electron diffraction patterns of Ta₉₇Te₆₀ and YbSi_1.41.

Electron diffraction pattern of single crystals — Electron diffraction patterns of Ta₉₇Te₆₀ along two perpendicular directions. The parameters of the tetragonal unit cell can be determined from these SAED patterns: a = 27.6, c= 20.6 Å.

Electron diffraction pattern of single crystals — Electron diffraction pattern of YbSi_1.41 along [001]. The reflection condition h+k=2n for hkl (C face centering) is fulfilled.

Ring Patterns

Electron diffraction patterns of polycrystaline material show ring patterns.

Electron diffraction pattern of platinum nanoparitcles — ED pattern of polycrystalline platinum. The indices are assigned to the diffraction rings in accordance of the face-centered cubic lattice of Pt (reflection condition: h,k,l all even or all odd).
