X-ray Crystallography02:18

X-ray Crystallography

24.5K
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

4.2K
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...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Optics

Background:

  • Understanding materials' structural dynamics is crucial for advancing electronic and quantum materials.
  • Existing methods lack fine spatial resolution for studying light-induced structural changes.

Purpose of the Study:

  • Introduce and validate a novel technique, optical transient grating X-ray diffraction (TGXD), for probing material structural dynamics.
  • Enhance spatial resolution and direct structural sensitivity in studying light-excited materials.

Main Methods:

  • Utilized an optical transient grating pump and focused X-ray diffraction probe (TGXD).
  • Applied modulated light with a controlled spatial profile to excite thin-film samples (BiFeO3 and FeRh).
  • Analyzed structural evolution and energy transport using focused X-ray diffraction.

Main Results:

  • Demonstrated TGXD on epitaxial BiFeO3, showing photoinduced strain proportional to optical fluence and microsecond-scale relaxation.
  • Observed deviations from sinusoidal excitation in FeRh, indicating higher-order spatial frequencies and location-dependent relaxation during a magnetostructural phase transformation.
  • Resolved mesoscopic energy transport and spatiotemporal heat flow in FeRh using the focused X-ray probe.

Conclusions:

  • TGXD provides unprecedented spatial resolution for characterizing light-induced structural dynamics.
  • The technique successfully reveals complex spatiotemporal energy transport in functional materials.
  • TGXD offers a model-independent approach to studying mesoscopic energy transport.
