AMORPHOUS & NANOCRYSTALLINE MATERIALS

Amorphous and nanocrystalline materials local order can be analyzed with ASTAR and e-PDF (electron Pair Distribution function) techniques. e-PDF can be acquired with any TEM and can be applied to characterize amorphous semiconductors, glass, amorphous minerals , battery materials and in situ studies in liquids in environmental cells.
