English

Subject field(s)
  • Chemistry
DEF

Any technique which is based on the diffraction of high energy electrons ... in crystalline materials and evaluation of the angular distribution of the transmitted electrons.

OBS

The diffraction pattern represents an image of the reciprocal lattice and therefore contains information about crystal structure.

OBS

This technique is often called selected area electron diffraction (SAED). For consistency with other electron diffraction techniques however the THEED is recommended.

French

Domaine(s)
  • Chimie
DEF

Toute technique fondée sur la diffraction d'électrons de hautes énergies [...] par des matériaux cristallins et l'évaluation de la distribution angulaire des électrons transmis.

OBS

Le diagramme de diffraction représente une image du réseau réciproque et il contient donc des informations sur la structure cristalline.

OBS

On désigne souvent cette technique sous le nom de diffraction (fine) d'électrons transmis de haute énergie (SAED). Afin de rendre la nomenclature cohérente avec celle des autres techniques de diffraction, il est plutôt recommandé d'utiliser ici l'expression "diffraction d'électrons transmis de haute énergie" (THEED).
