P doped random C20 fullerite - model structure for fullerene-like CPx [PDF]

, 2013
Carbon-based amorphous and fullerene-like (FL) thin films have a great potential due to their mechanical resiliency. TEM investigation and interpretation of results from FL structures embedded in bulk phases is not straightforward.

Virtual-diagnostic-based time stamping for ultrafast electron diffraction

Physical Review Accelerators and Beams, 2023
In this work, nondestructive virtual diagnostics are applied to retrieve the electron beam time of arrival and energy in a relativistic ultrafast electron diffraction (UED) beamline using independently measured machine parameters.

Imaging Molecular Structure through Femtosecond Photoelectron Diffraction on Aligned and Oriented Gas-Phase Molecules [PDF]

, 2014
This paper gives an account of our progress towards performing femtosecond time-resolved photoelectron diffraction on gas-phase molecules in a pump-probe setup combining optical lasers and an X-ray Free-Electron Laser.

Femtosecond time-resolved MeV electron diffraction

New Journal of Physics, 2015
We report the experimental demonstration of femtosecond electron diffraction using high-brightness MeV electron beams. High-quality, single-shot electron diffraction patterns for both polycrystalline aluminum and single-crystal 1T-TaS _2 are obtained ...

Texture, twinning and metastable "tetragonal" phase in ultrathin films of HfO₂ on a Si substrate [PDF]

, 2009
Thin HfO₂ films grown on the lightly oxidised surface of (100) Si wafers have been examined using dark-field transmission electron microscopy and selected area electron diffraction in plan view.

Convergent-beam electron diffraction

Acta Crystallographica Section A Foundations of Crystallography, 1989
Symmetry determination of three-dimensional (usual) crystals, four-dimensional (one-dimensionally incommensurate) crystals and five- and six-dimensional crystals (quasicrystals) by convergent-beam electron diffraction is described and demonstrated using real materials.

High pressure minerals in the Château-Renard (L6) ordinary chondrite: implications for collisions on its parent body [PDF]

, 2018
We report the first discoveries of high-pressure minerals in the historical L6 chondrite fall Château-Renard, based on co-located Raman spectroscopy, scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy and electron backscatter ...

Coherent Electron Source for Ultrafast Electron Diffraction and Imaging

EPJ Web of Conferences, 2013
We numerically investigate the suitability of photoexcited nanotips as a source of coherent femtosecond single electron pulses for ultrafast surface-sensitive electron diffraction and non-destructive imaging with low-energy electrons.
