Ewald construction for 2D diffraction (original) (raw)

Ewald construction for 2D diffraction image/svg+xml Ewald construction for 2D diffraction 2020-06-13 Ivo Pletikosic Low-energy electron diffraction LEED Ewald construction Condensed matter physics Wave vector components parallel to the surface of the incoming (ki) and outcoming (kf) elastically diffracted electrons from a 2D lattice differ by the reciprocal lattice vector G(hk). Ewald construction shows which diffracted reflections are possible. For clarity, only half of the Ewald sphere is shown.
