Surface structure angle resolved mode

In the angle resolved mode, which selects electrons traveling in well-defined directions, emphasis is laid on the properties of plane-wave diffraction within the surface — this provides access to all interplanar distances (not only between atomic planes parallel to the surface) and thus, to the complete three-dimensional crystallographic structure (as for example in LEED and in ARPES). Significant structural information can come from steps 1 and 4.
