MS-56: Analysis of the fine structure in electron diffraction data
Invited: Paul Voyles (USA), Cheuk-Wai Tai (Sweden) | ||
| Session Abstract | ||
|
In a disordered or amorphous material, the atomic arrangement does not follow a strict lattice rule; therefore, it is in principle impossible to know exact atomic composition at a specified point. Application of Pair Distribution Function (PDF) on electron diffraction data provides viable tool for study the structure of such materials. Especial importance of this method is its applicability to study local disorder and nanomaterials.
