Atomically resolved three dimensional images from surfaces
Abstract
Full hemispherical Al 2s (E_kin =950 eV) diffraction patterns from Al(111) have been measured for two different orientations of the light polarisation relative to the detector; the far node and the near node geometry. The holographic interpretation of the two patterns show a strongly enhanced image quality for the near node data set. The 12 nearest neighbors of the emitters are clearly resolved whereas in the off node geometry no atomic positions can be assigned. The new approach of Near Node Photoelectron Holography [1] has thus the potential of directly determining the atomic structure of molecular objects with a size in the order of 10 ÅP>[1] T.
