Electron diffraction of tilted perovskites [PDF]
Acta Crystallographica Section B Structural Science, 2005 Simulations of electron diffraction patterns for each of the known perovskite tilt systems have been performed. The conditions for the appearance of superlattice reflections arising from rotations of the octahedra are modified to take into account ...

Electron Diffraction by Vapours [PDF]
Nature, 1933 DURING the last two years, a practical method has been evolved for obtaining good photographs of the diffraction of 30–55 kv. electrons by vapours. I now get satisfactory results with any substance the vapour pressure of which exceeds 10 cm. of mercury at 750° C.

Reaching the potential of electron diffraction. [PDF]
Cell Rep Phys SciMicrocrystal electron diffraction (MicroED) is an emerging structural technique in which submicron crystals are used to generate diffraction data for structural studies. Structures allow for the study of molecular-level architecture and drive hypotheses about modes of action, mechanisms, dynamics, and interactions with other molecules.

Femtosecond single-electron diffraction [PDF]
Structural Dynamics, 2014 Ultrafast electron diffraction allows the tracking of atomic motion in real time, but space charge effects within dense electron packets are a problem for temporal resolution. Here, we report on time-resolved pump-probe diffraction using femtosecond single-electron pulses that are free from intra-pulse Coulomb interactions over the entire trajectory ...

Ultrafast electron diffraction using an ultracold source [PDF]
, 2014 We present diffraction patterns from micron-sized areas of mono-crystalline graphite obtained with an ultracold and ultrafast electron source. We show that high spatial coherence is manifest in the visibility of the patterns even for picosecond bunches ...

Single-Shot Electron Diffraction using a Cold Atom Electron Source [PDF]
, 2015 Cold atom electron sources are a promising alternative to traditional photocathode sources for use in ultrafast electron diffraction due to greatly reduced electron temperature at creation, and the potential for a corresponding increase in brightness ...

Electron diffraction by plasmon waves [PDF]
Physical Review B, 2016 An electron beam traversing a structured plasmonic field is shown to undergo diffraction with characteristic angular patterns of both elastic and inelastic outgoing electron components. In particular, a plasmonic {\it grating} (e.g., a standing wave formed by two counter-propagating plasmons in a thin film) produces diffraction orders of the same ...

Electron diffraction by vacuum fluctuations
New Journal of Physics, 2020 Abstract 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 integral analysis.

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