Electron Diffraction - Examples

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 YbSi1.41 along [001]. The reflection condition h+k=2n for hkl (C face centering) is fulfilled.

 

Ring Patterns

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).
