Quantitative size-dependent structure and strain determination of CdSe nanoparticles using atomic pair distribution function analysis
The size-dependent structure of CdSe nanoparticles, with diameters ranging from 2 to 4 nm, has been studied using the atomic pair distribution function PDF method. The core structure of the measured CdSe nanoparticles can be described in terms of the wurtzite atomic structure with extensive stacking faults. The density of faults in the nanoparticles is 50%. The diameter of the core region was e...
متن کاملConfirmation of disordered structure of ultrasmall CdSe nanoparticles from X-ray atomic pair distribution function analysis.
The atomic pair distribution function (PDF) analysis of X-ray powder diffraction data has been used to study the structure of small and ultra-small CdSe nanoparticles. A method is described that uses a wurtzite and zinc-blende mixed phase model to account for stacking faults in CdSe particles. The mixed-phase model successfully describes the structure of nanoparticles larger than 2 nm yielding ...
متن کاملLocal 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 کاملQuantitative Structural Analysis of Nanoparticles Using Electron Pair Distribution Function (ePDF)
Quantitatively determining the atomic arrangement of nanomaterials is essential in nanoscience. While the traditional method of X-ray crystallography fails because of limited size of coherent structural domains within nanomaterials, a specialized approach, known as the atomic pair distribution function (PDF) method, has emerged as a powerful tool to obtain quantitative 3D structural information...
