Local Atomic Structure Analysis Using the Atomic Pair Distribution Method
Powder diffraction is a major component of any condensed matter scientist’s arsenal, providing the investigator a way to directly map the location of atoms inside of a material. The most common diffraction experiments provide insights into the average atomic structure of materials, which can break down when materials have lowered local symmetry, or are disordered. Analysis of the pair distribut...
متن کاملStructure of nanocrystalline Ti3C2 MXene using atomic pair distribution function.
The structures of nanocrystalline pristine, potassium hydroxide and sodium acetate intercalated new two-dimensional materials Ti3C2 MXenes were studied using the x-ray atomic pair distribution function technique. Pristine MXene has a hexagonal structure with a=b=3.0505(5) Å, c=19.86(2) Å (S.G. P63/mmc No. 194). Both hydroxyl and fluoride terminating species are present. The intercalation of K...
متن کاملThe atomic pair distribution function: past and present
The history of the PDF method is briefly reviewed. Recent results, principally from the Billinge group, are also reviewed.
متن کاملNanostructure studied using the atomic pair distribution function
Studying the atomic structure of nanostructured materials presents a special challenge because our extensive crystallographic toolbox begins to lose its power on the nanoscale. The presumption of periodicity is a poor approximation when structural correlation lengths are limited to a few tens of nanometres or less and alternative approaches are needed. Here we give an overview of recent results...
متن کاملAtomic pair distribution functions analysis of disordered low-Z materials.
Results of high-energy X-ray diffraction experiments coupled to atomic pair distribution function analysis of disordered low-Z materials are presented. Several scientifically and technologically important classes of disordered low-Z materials such as small and large organic molecules, graphitic powders, polymers and liquids are intentionally explored to certify the technique's performance. Resu...
