X-ray Crystallography02:18

X-ray Crystallography

23.9K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples

3.8K
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are  scattered by the electron clouds around the sample atoms. The  X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Lattice Centering and Coordination Number

9.6K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

The de Broglie Wavelength

25.9K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Metallic Solids02:37

Metallic Solids

18.4K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Summary
This summary is machine-generated.

Diffuse intensities in electron diffraction patterns from face-centered cubic (fcc) materials are often caused by higher-order Laue zone reflections, not complex defects. This finding simplifies the interpretation of electron diffraction data for various fcc alloys.

Area of Science:

  • Materials Science
  • Crystallography
  • Electron Microscopy

Background:

  • Interpreting diffuse intensities in electron diffraction patterns is complex for multi-principal element alloys.
  • Previously, diffuse intensities in face-centered cubic (fcc) alloys were attributed to short-range order, medium-range order, or various planar defects.
  • These interpretations pose challenges in accurately characterizing material structures.

Purpose of the Study:

  • To demonstrate that many observed diffuse intensities in electron diffraction patterns of fcc materials originate from higher-order Laue zone (HOLZ) reflections.
  • To provide a theoretical explanation and experimental validation for HOLZ reflections causing diffuse intensities.
  • To offer a framework for distinguishing HOLZ reflections from defect-induced intensities.

Main Methods:

  • Analysis of electron diffraction patterns from various fcc materials, including CdTe, pure Ni, and pure Al.
  • Application of electron diffraction theory to model and explain the observed diffuse intensities.
  • Comparison of calculated HOLZ reflection intensities with experimental data.

Main Results:

  • Diffuse intensities, specifically {422} and {311} reflections in selected area diffraction patterns, are identified as HOLZ reflections.
  • Similar HOLZ reflection features were observed across different zone axes in a range of fcc materials.
  • Calculated HOLZ intensities closely matched observed intensities, confirming their universality in fcc materials.

Conclusions:

  • Higher-order Laue zone reflections are a common source of diffuse intensities in electron diffraction patterns of fcc materials.
  • This understanding simplifies the interpretation of complex diffraction data, reducing misattribution to short-range or medium-range order.
  • The study provides a robust framework for accurately identifying and locating diffuse intensities in electron diffraction analysis.
