Abstract Scanning precession electron diffraction involves the acquisition of a two-dimensional precession electron diffraction pattern at every probe position in a two-dimensional scan. Publications (39,162). The data typically comprise many more diffraction patterns than the number of distinct microstructural volume elements (. crystals) in the region sampled View.

Precession electron diffraction (PED) is a specialized method to collect electron diffraction patterns in a transmission electron microscope (TEM). By rotating (precessing) a tilted incident electron beam around the central axis of the microscope, a PED pattern is formed by integration over a collection of diffraction conditions. This produces a quasi-kinematical diffraction pattern that is more suitable as input into direct methods algorithms to determine the crystal structure of the sample.

The resolution limitations in microscopy are often referred to as the diffraction barrier, which restricts the ability of optical instruments to distinguish between two objects separated by a lateral distance less than.

The resolution limitations in microscopy are often referred to as the diffraction barrier, which restricts the ability of optical instruments to distinguish between two objects separated by a lateral distance less than approximately half the wavelength of light used to image the specimen. The optical microscope has played a central role in helping to untangle the complex mysteries of biology ever since the seventeenth century when Dutch inventor Antoni van Leeuwenhoek and English scientist Robert Hooke first reported observations using single-lens and compound microscopes, respectively.

Electron diffraction refers to the wave nature of electrons. However, from a technical or practical point of view, it may be regarded as a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon is commonly known as wave–particle duality, which states that a particle of matter (in this case the incident electron) can be described as a wave.

Electron diffraction in a TEM requires that the sample be at a thickness no greater than 100 nm. Specimen preparation must be done very carefully and it is time consuming. Also, the thin section of the sample can be damaged by the electron beam during examination in the TEM. Crystallographic structural information can be obtained with high accuracy by electron diffraction, but the right experimental conditions are essential and interpreting the data is nontrivial and nonroutine.
