Elektronenbeugung an Vizinalflächen und an Kugelflächen von Einkristallen / Electron Diffraction of Vicinals and of Spherically Shaped Crystal Surfaces

Abstract

The reciprocal lattice of a periodic terrace-ledge surface is calculated by Fourier transformation. This formalism is applied to spherical crystals. In that case the reciprocal lattice consists of bundles of finite streaks; their vertices are situated on the reciprocal lattice points of the bulk crystal. That confirms a model formerly used to discuss LEED experiments with spherical crystals. The calculation is generalized to describe terraces composed of several monolayers.
