THE EFFECTS OF VARIOUS EXPERIMENTAL PARAMETERS ON THE ACCURACY OF PHOTOEMISSION HOLOGRAPHY

Experimental and theoretically simulated Auger electron diffraction patterns are studied to determine the effects of several experimental parameters on the holographic images generated from these patterns. Among the parameters examined are the experimental angular resolution, electron kinetic energy, and total collection solid angle of the diffraction pattern. Several techniques of combining the images from diffraction patterns taken at different kinetic energies are critically analyzed and compared. The origin of small radius "forward scattering artifacts" in the holographic images is discussed. A technique for removing these artifacts is introduced which requires no prior knowledge of the structure being studied.
