Electron diffraction using transmission electron microscopy

open access: yesJournal of Research of the National Institute of Standards and Technology, 2001
Electron diffraction via the transmission electron microscope is a powerful method for characterizing the structure of materials, including perfect crystals and defect structures. The advantages of electron diffraction over other methods, e.g., x-ray or neutron, arise from the extremely short wavelength (≈2 pm), the strong atomic scattering, and the ...

X-Ray sum frequency generation; direct imaging of ultrafast electron dynamics [PDF]

open access: yes, 2018
X-ray diffraction from molecules in the ground state produces an image of their charge density, and time-resolved X-ray diffraction can thus monitor the motion of the nuclei.

Electron diffraction by vacuum fluctuations

open access: yesNew Journal of Physics, 2020
Vacuum fluctuations are known to produce electron diffraction leading to decoherence and self-interference. These effects have so far been studied as either an extension of the Aharonov–Bohm effect in front of a planar perfect conductor or through path ...

Formation of a stable deacagonal quasicrystalline Al-Pd-Mn surface layer [PDF]

open access: yes, 2001
We report the in situ formation of an ordered equilibrium decagonal Al-Pd-Mn quasicrystal overlayer on the 5-fold symmetric surface of an icosahedral Al-Pd-Mn monograin.

Ultrafast electron diffraction of THz-excited nanostructures [PDF]

open access: yesEPJ Web of Conferences, 2019
We study the electromagnetic response of nanostructures to single-cycle THz excitation by using ultrafast electron diffraction. Although the nanostructures themselves are static, there exist complex sub-THz-cycle Bragg spot dynamics that relate via time ...

Electron Backscatter Diffraction Study of Ultrahigh-Pressure Tso Morari Eclogites (Trans-Himalayan Collisional Zone): Implications for Strain Regime Transition from Constrictional to Plane Strain during Exhumation

open access: yesLithosphere, 2022
The Tso Morari Crystalline Complex (TMCC) of trans-Himalaya (eastern Ladakh, India) contains enclaves of ultrahigh-pressure eclogites that underwent deep burial (≥80 km) and subsequent rapid exhumation during continental subduction, collision, and final ...

Exploring transmission Kikuchi diffraction using a Timepix detector [PDF]

open access: yes, 2017
Electron backscatter diffraction (EBSD) is a well-established scanning electron microscope (SEM)-based technique [1]. It allows the non-destructive mapping of the crystal structure, texture, crystal phase and strain with a spatial resolution of tens of ...

Annealing-induced reduction in nanoscale heterogeneity of thermally evaporated amorphous As2S3 films [PDF]

open access: yes, 2015
The morphology and structural order of thermally deposited and annealed amorphous As2S3 films have been investigated using high resolution transmission electron microscopy.

Controlled double-slit electron diffraction

open access: yesNew Journal of Physics, 2013
Double-slit diffraction is a corner stone of quantum mechanics. It illustrates key features of quantum mechanics: interference and the particle-wave duality of matter. In 1965, Richard Feynman presented a thought experiment to show these features.

Low-energy electron diffraction from disordered surfaces [PDF]

open access: yes, 1978
Model calculations are presented of L E E D intensities diffracted by a onedimensionally disordered overlayer adsorbed on a well ordered substrate. Multiple scattering amplitudes are calculated by an extension of Beeby's multiple scattering method ...
