Electron Spectroscopic Diffraction

Ultramicroscopy, 1990
In principle, electron diffraction studies in a transmission electron microscope (TEM) provide much the same crystallographic information as does X-ray or neutron diffraction. Compared to the latter two, two important problems arise in electron diffraction owing to the much stronger interaction of electrons with matter: 1) The kinematical ...

Precession Electron Diffraction

2012
Abstract Precession electron diffraction is considered a key technique available to electron microscopists to elucidate the structure of a wide variety of crystals. Although originally envisaged as a method to produce integrated intensities that could be used for structure solution and refinement, precession electron diffraction has proved much more ...

Electron Diffraction and Crystallography

2001
Reciprocal lattices of materials are spanned by three reciprocal-lattice vectors, so the diffraction patterns of materials are inherently three-dimensional. To obtain all available diffraction information, the diffraction intensity should be measured for all magnitudes and orientations of the three-dimensional diffraction vector, Δ k, with coordinates ...

Electron diffraction of membranes

Biophysik, 1971
Electron diffraction conducted on myelin membranes, photosynthetic and photoreceptor membranes yielded spot diffraction patterns indicating an ordered state of membranes; the interplanar spacings being of the order of A units. It was observed, too, that a membrane specimen accommodates different space structures. Based on these findings it is suggested

Electron-diffraction transistors

Proceedings., IEEE/Cornell Conference on Advanced Concepts in High Speed Semiconductor Devices and Circuits, 2003
The design, fabrication, and applications of QUADFETs (quantum diffraction field effect transistors) are described. The QUADFETs will enable Fraunhofer diffraction to be demonstrated and exploited. These devices are high-electron-mobility transistors (HEMTs), in which the source and a specially formed drain perform the functions of the light source and

Inelastic diffraction of electrons

AIP Conference Proceedings, 1996
We have measured the angular distribution of electrons reflected from Cu(001) having excited: i) an interband transition, ii) a plasmon, and iii) a core electron. We have found that the angular patterns in cases i) and ii) are similar to the angular pattern of elastically reflected electrons; in particular, the inelastic electrons are reflected along ...
