Recrystallization: Solid–Solution Equilibria01:10

Recrystallization: Solid–Solution Equilibria

Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...
X-ray Crystallography02:18

X-ray Crystallography

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...
Polymer Classification: Crystallinity01:21

Polymer Classification: Crystallinity

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

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...

Imperfections in Crystal Structure: Point, Line and Plane Defects

A perfect crystal, in theory, has a uniform structure with the same unit cell and lattice points throughout. However, any deviation from this periodic arrangement is known as an imperfection or defect. These defects can be categorized into three types: point, line, and plane defects.Point defects occur when there is a deviation from the ideal due to missing atoms, displaced atoms, or additional atoms. These imperfections might occur due to imperfect packing during crystallization or because of...
Determination of Crystal Structures01:29

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Summary
This summary is machine-generated.

Low-energy ion implantation in silicon (Si) creates disordered regions, not just point defects. Dynamic annealing and recrystallization control defect formation even after low-energy recoils.

Area of Science:

  • Materials Science
  • Computational Physics
  • Solid-State Chemistry

Background:

  • Conventional understanding posits high-energy recoils in silicon (Si) form amorphous regions, while low-energy recoils yield isolated point defects.
  • The dynamic processes governing defect evolution after ion implantation in crystalline Si are not fully elucidated.

Purpose of the Study:

  • To investigate the atomic-scale response of crystalline Si to low-kinetic-energy recoils.
  • To challenge the prevailing model of defect formation following low-energy ion implantation.

Main Methods:

  • Utilized dynamical density-functional calculations to simulate recoil events in crystalline Si.
  • Analyzed the evolution of atomic structure and defect formation over femtosecond timescales.

Main Results:

  • Demonstrated that recoils significantly below 1 keV induce highly disordered regions in Si.
  • Observed that these disordered regions persist for hundreds of femtoseconds.
  • Highlighted the role of dynamic annealing and recrystallization in defect evolution.

Conclusions:

  • The formation of amorphous-like regions is not exclusive to high-energy recoils in Si.
  • Dynamic recrystallization processes significantly influence defect formation during low-energy ion implantation.
  • Revises the understanding of ion-induced defect formation mechanisms in crystalline semiconductors.
