Structure refinement from precession electron diffraction data.
Electron diffraction is a unique tool for analysing the crystal structures of very small crystals. In particular, precession electron diffraction has been shown to be a useful method for ab initio structure solution. In this work it is demonstrated that precession electron diffraction data can also be successfully used for structure refinement, if the dynamical theory of diffraction is used for...
متن کاملCombining precession electron diffraction data with X-ray powder diffraction data to facilitate structure solution
Information derived from precession electron diffraction (PED) patterns can be used to advantage in combination with high-resolution X-ray powder diffraction data to solve crystal structures that resist solution from X-ray data alone. PED data have been exploited in two different ways for this purpose: (1) to identify weak reflections and (2) to estimate the phases of the reflections in the pro...
متن کاملOn the Use of Precession Electron Diffraction for Minerals Characterization: From Twinning Identification to Structure Refinement
The precession electron diffraction (PED) technique [1] has been originally developed for structure determination at a submicrometer scale in a transmission electron microscope (TEM). Since, many structures have been solved using PED, recently combined with the tomographic acquisition of 3D electron diffraction data [2]. Using PED, integrated intensities of the diffracted beams as a function of...
متن کاملAberration-corrected precession electron diffraction
Precession electron diffraction (PED) is a promising technique for collecting high quality diffraction patterns for rapid nanoscale structural characterization [1]. It is able to reduce dynamical scattering effects, improving the interpretability of diffraction intensities over those obtained by conventional electron diffraction techniques. When used on a microscope that can produce a fine prob...
متن کاملPrecession electron diffraction – a topical review
In the 20 years since precession electron diffraction (PED) was introduced, it has grown from a little-known niche technique to one that is seen as a cornerstone of electron crystallography. It is now used primarily in two ways. The first is to determine crystal structures, to identify lattice parameters and symmetry, and ultimately to solve the atomic structure ab initio. The second is, throug...
